They aren't going anywhere, and probing on DDC can cause the panel to blank briefly, so read them up front and cache them for later queries. v2: fix potential NULL derefs in intel_dp_get_edid_modes and intel_dp_get_edid (Jani) copy full EDID length, including extension blocks (Takashi) free EDID on teardown (Takashi) v3: malloc a new EDID buffer that's big enough for the memcpy (Chris) v4: change handling of NULL EDIDs, just preserve the NULL behavior across detects and mode list fetches rather than trying to re-fetch the EDID (Chris) v5: be glad that Chris is around to remind me to hit C-x C-s before committing.

2012-06-16Revert "drm/i915/dp: Use auxch precharge value of 5 everywhere"Daniel Vetter
This reverts commit 092945e11c5b84f66dd08f0b87fb729715d377bc. This commit prevents a DP screen from properly training the link. Oddly enough it works, once the machine has been warm-booted with an older kernel. According to DP docs this _should_ have been the right precharge time. Also, the commit that originally introduces this was just general snb DP enabling and didn't mention any specific reason for this special value. Whatever, trust the reporter that this makes things worse and let's just revert it. v2: Less spelling fail.

2012-06-14USB: fix gathering of interface associationsDaniel Mack
TEAC's UD-H01 (and probably other devices) have a gap in the interface number allocation of their descriptors: Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 220 bNumInterfaces 3 [...] Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 [...] Interface Association: bLength 8 bDescriptorType 11 bFirstInterface 2 bInterfaceCount 2 bFunctionClass 1 Audio bFunctionSubClass 0 bFunctionProtocol 32 iFunction 4 Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 2 bAlternateSetting 0 [...] Once a configuration is selected, usb_set_configuration() walks the known interfaces of a given configuration and calls find_iad() on each of them to set the interface association pointer the interface is included in. The problem here is that the loop variable is taken for the interface number in the comparison logic that gathers the association. Which is fine as long as the descriptors are sane. In the case above, however, the logic gets out of sync and the interface association fields of all interfaces beyond the interface number gap are wrong. Fix this by passing the interface's bInterfaceNumber to find_iad() instead.

2012-06-13Fix OMAP EHCI suspend/resume failure (i693)Anand Gadiyar
Its observed with some PHY, the 60Mhz clock gets cut too soon for OMAP EHCI, leaving OMAP-EHCI in a bad state. So on starting port suspend, make sure the 60Mhz clock to EHCI is kept alive using an internal clock, so that EHCi can cleanly transition its hw state machine on a port suspend. Its not proven if this is the issue hit on USB3333, but the symptoms look very similar.

git://git.kernel.org/pub/scm/linux/kernel/git/sarah/xhci into usb-linus xhci: Bug fixes for 3.5 Hi Greg, Here's five bug fixes for 3.5. They fix some memory leaks in the bandwidth calculation code, fix a couple bugs in the USB3 Link PM patchset, and make system suspend and resume work on platforms with the AsMedia ASM1042 xHCI host controller.

2012-06-13xHCI: Increase the timeout for controller save/restore state operationAndiry Xu
When system software decides to power down the xHC with the intent of resuming operation at a later time, it will ask xHC to save the internal state and restore it when resume to correctly recover from a power event. Two bits are used to enable this operation: Save State and Restore State. xHCI spec 4.23.2 says software should "Set the Controller Save/Restore State flag in the USBCMD register and wait for the Save/Restore State Status flag in the USBSTS register to transition to '0'". However, it does not define how long software should wait for the SSS/RSS bit to transition to 0. Currently the timeout is set to 1ms. There is bug report (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1002697) indicates that the timeout is too short for ASMedia ASM1042 host controller to save/restore the state successfully. Increase the timeout to 10ms helps to resolve the issue. This patch should be backported to stable kernels as old as 2.6.37, that contain the commit 5535b1d5f8885695c6ded783c692e3c0d0eda8ca "USB: xHCI: PCI power management implementation" Signed-off-by: Andiry Xu <andiry.xu@gmail.com> Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Cc: Ming Lei <ming.lei@canonical.com> Cc: stable@vger.kernel.org
2012-06-13xhci: Don't free endpoints in xhci_mem_cleanup()Takashi Iwai
This patch fixes a few issues introduced in the recent fix [f8a9e72d: USB: fix resource leak in xhci power loss path] - The endpoints listed in bw table are just links and each entry is an array member of dev->eps[]. But the commit above adds a kfree() call to these instances, and thus it results in memory corruption. - It clears only the first entry of rh_bw[], but there can be multiple ports. - It'd be safer to clear the list_head of ep as well, not only removing from the list, as it's checked in xhci_discover_or_reset_device(). This patch should be backported to kernels as old as 3.2, that contain the commit 839c817ce67178ca3c7c7ad534c571bba1e69ebe "xhci: Store information about roothubs and TTs."

xhci_free_tt_info() may access the invalid memory when it removes the last entry but the list is not empty. Then tt_next reaches to the list head but it still tries to check the tt_info of that entry. This patch fixes the bug and cleans up the messy code by rewriting with a simple list_for_each_entry_safe().

2012-06-13bnx2x: fix checksum validationEric Dumazet
bnx2x driver incorrectly sets ip_summed to CHECKSUM_UNNECESSARY on encapsulated segments. TCP stack happily accepts frames with bad checksums, if they are inside a GRE or IPIP encapsulation. Our understanding is that if no IP or L4 csum validation was done by the hardware, we should leave ip_summed as is (CHECKSUM_NONE), since hardware doesn't provide CHECKSUM_COMPLETE support in its cqe. Then, if IP/L4 checksumming was done by the hardware, set CHECKSUM_UNNECESSARY if no error was flagged.

2012-06-13USB: serial-generic: use a single set of device IDsAlan Stern
The usb-serial-generic driver uses different device IDs for its USB matching and its serial matching. This can lead to problems: The driver can end up getting bound to a USB interface without being allowed to bind to the corresponding serial port. This patch (as1557) fixes the problem by using the same device ID table (the one that can be altered by the "vendor=" and "product=" module parameters) for both purposes. The unused table is removed. Now the driver will bind only to the intended devices.

The reason for the above is simple: The USB driver probe will succeed if *any* registered serial driver matches, and will use that serial driver for all serial driver functions. This makes ref counting go wrong. We count the USB driver as used, but not the USB serial driver.

2012-06-13USB: add NO_D3_DURING_SLEEP flag and revert 151b61284776be2Alan Stern
This patch (as1558) fixes a problem affecting several ASUS computers: The machine crashes or corrupts memory when going into suspend if the ehci-hcd driver is bound to any controllers. Users have been forced to unbind or unload ehci-hcd before putting their systems to sleep. After extensive testing, it was determined that the machines don't like going into suspend when any EHCI controllers are in the PCI D3 power state. Presumably this is a firmware bug, but there's nothing we can do about it except to avoid putting the controllers in D3 during system sleep. The patch adds a new flag to indicate whether the problem is present, and avoids changing the controller's power state if the flag is set. Runtime suspend is unaffected; this matters only for system suspend. However as a side effect, the controller will not respond to remote wakeup requests while the system is asleep. Hence USB wakeup is not functional -- but of course, this is already true in the current state of affairs. A similar patch has already been applied as commit 151b61284776be2d6f02d48c23c3625678960b97 (USB: EHCI: fix crash during suspend on ASUS computers). The patch supersedes that one and reverts it. There are two differences: The old patch added the flag at the USB level; this patch adds it at the PCI level. The old patch applied to all chipsets with the same vendor, subsystem vendor, and product IDs; this patch makes an exception for a known-good system (based on DMI information).

2012-06-12tcm_qla2xxx: Handle malformed wwn strings properlyRoland Dreier
If we make a variable an unsigned int and then expect it to be < 0 on a bad character, we're going to have a bad time. Fix the tcm_qla2xxx code to actually notice if hex_to_bin() returns a negative variable. This was detected by the compiler warning: scsi/qla2xxx/tcm_qla2xxx.c: In function ‘tcm_qla2xxx_npiv_extract_wwn’: scsi/qla2xxx/tcm_qla2xxx.c:148:3: warning: comparison of unsigned expression >= 0 is always true [-Wtype-limits] Signed-off-by: Roland Dreier <roland@purestorage.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
