2010-07-27gpio: fix spurious printk when freeing a gpioJon Povey
When freeing a gpio that has not been exported, gpio_unexport() prints a debug message when it should just fall through silently.

Commit 0ede76fcec5415ef82a423a95120286895822e2d, "USB: remove uses of URB_NO_SETUP_DMA_MAP" introduced a regression by inadvertantly removing initialization of the transfer flags. This caused initialization failures in the ums-karma driver. Fix the regression by zeroing it. While at it, as Alan Stern points out, the initializers for actual_length and status are handled by the core and error_count only matters for isochronous urbs, so they don't need to be set here. Remove them. Signed-off-by: Bob Copeland <me@bobcopeland.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-07-26USB: xhci: Set Mult field in endpoint context correctly.Sarah Sharp
The bmAttributes field of the SuperSpeed Endpoint Companion Descriptor has different meanings, depending on the endpoint type. If the endpoint is isochronous, the bmAttributes field is the maximum number of packets within a service interval that this endpoint supports. If the endpoint is bulk, it's the number of stream IDs this endpoint supports. Only set the Mult field of the xHCI endpoint context using the bmAttributes field if the endpoint is isochronous, and the device is a SuperSpeed device.

When an attempt is made to read the interface strings of the Artisman Watchdog USB dongle (idVendor:idProduct 04b4:0526) an error is written to the dmesg log (uhci_result_common: failed with status 440000) and the dongle resets itself, resulting in a disconnect/reconnect loop. Adding the dongle to the list of devices in quirks.c, with the same quirk Alan Stern's previous patch for the Saitek Cyborg Gold 3D joystick, stops the device from resetting and allows it to be used with no problems.

2010-07-26USB: xhci: Set EP0 dequeue ptr after reset of configured device.Sarah Sharp
When a configured device is reset, the control endpoint's ring is reused. If control transfers to the device were issued before the device is reset, the dequeue pointer will be somewhere in the middle of the ring. If the device is then issued an address with the set address command, the xHCI driver must provide a valid input context for control endpoint zero. The original code would give the hardware the original input context, which had a dequeue pointer set to the top of the ring. This would cause the host to re-execute any control transfers until it reached the ring's enqueue pointer. When issuing a set address command for a device that has just been configured and then reset, use the control endpoint's enqueue pointer as the hardware's dequeue pointer. Assumption: All control transfers will be completed or cancelled before the set address command is issued to the device. If there are any outstanding control transfers, this code will not work.

2010-07-26USB: Fix USB3.0 Port Speed Downgrade after port resetSarah Sharp
Without this fix, a USB 3.0 port is downgraded to full speed after a port reset of a configured device. The USB 3.0 terminations will be disabled permanently, and USB 3.0 devices will always enumerate as full speed devices, until the host controller is unplugged (if it is an ExpressCard) or the computer is rebooted. Fajun Chen traced this traced the speed downgrade issue to the port reset and the interpretation of port status in USB hub driver code. The hub code was not testing for the port being a SuperSpeed port, and it fell through to the else case of Full Speed. The following patch adds SuperSpeed mapping from the port status, and fixes the speed downgrade issue.

2010-07-26USB: xHCI: Fix another bug in link TRB activation change.Sarah Sharp
Commit 6c12db90f19727c76990e7f4801c67a148b30111 also seems to have introduced a bug that is triggered when the command ring is about to wrap. The inc_enq() function will not have moved the enqueue pointer past the link TRB. It is supposed to be moved past the link TRB in prepare_ring(), which should be called before a TD is enqueued. However, the queue_command() function never calls the prepare_ring() function because prepare_ring() is only supposed to be used for endpoint rings. That means the enqueue pointer will not be moved past the link TRB, and will get overwritten. The fix is to make queue_command() call prepare_ring() with a fake endpoint status (set to running). Then the enqueue pointer will get moved past the link TRB. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2010-07-26agp/intel: Use the correct mask to detect i830 aperture size.Tim Gardner
BugLink: https://bugs.launchpad.net/bugs/597075 commit f1befe71fa7a79ab733011b045639d8d809924ad introduced a regression when detecting aperture size of some i915 adapters, e.g., those on the Intel Q35 chipset. The original report: https://bugzilla.kernel.org/show_bug.cgi?id=15733 The regression report: https://bugzilla.kernel.org/show_bug.cgi?id=16294 According to the specification found at http://intellinuxgraphics.org/VOL_1_graphics_core.pdf, the PCI config space register I830_GMCH_CTRL is a mirror of GMCH Graphics Control. The correct macro for isolating the aperture size bits is therefore I830_GMCH_GMS_MASK along with the attendant changes to the case statement.

2010-07-26drm/i915: Use the correct scanout alignment for fbcon.Chris Wilson
This fixes a potential modesetting error during boot with plymouth on Broadwater and Crestline introduced with 9df47c. The framebuffer was hard-coding an alignment of 64K, but the modesetting code required the documented alignment of 128K. The result was that we would attempt to unbind the pinned fbcon buffer, triggering an ERROR and ultimately failing the mode change.

2010-07-26drm/i915: make sure eDP panel is turned onJesse Barnes
When enabling the eDP port, we need to make sure the panel is turned on after training the link. If we don't, it likely won't come back after suspend or may not come up at all. For unknown reasons, unlocking the panel regs before initiating a power on sequence is necessary. There are known bugs in the PCH panel sequencing logic, apparently this is one possible workaround.

2010-07-26drm/i915: Make G4X-style PLL search more permissiveAdam Jackson
Fixes an Ironlake laptop with a 68.940MHz 1280x800 panel and 120MHz SSC reference clock. More generally, the 0.488% tolerance used before is just too tight to reliably find a PLL setting. I extracted the search algorithm and modified it to find the dot clocks with maximum error over the valid range for the given output type: http://people.freedesktop.org/~ajax/intel_g4x_find_best_pll.c This gave: Worst dotclock for Ironlake DAC refclk is 350000kHz (error 0.00571) Worst dotclock for Ironlake SL-LVDS refclk is 102321kHz (error 0.00524) Worst dotclock for Ironlake DL-LVDS refclk is 219642kHz (error 0.00488) Worst dotclock for Ironlake SL-LVDS SSC refclk is 84374kHz (error 0.00529) Worst dotclock for Ironlake DL-LVDS SSC refclk is 183035kHz (error 0.00488) Worst dotclock for G4X SDVO refclk is 267600kHz (error 0.00448) Worst dotclock for G4X HDMI refclk is 334400kHz (error 0.00478) Worst dotclock for G4X SL-LVDS refclk is 95571kHz (error 0.00449) Worst dotclock for G4X DL-LVDS refclk is 224000kHz (error 0.00510) Signed-off-by: Adam Jackson <ajax@redhat.com> Cc: stable@kernel.org Signed-off-by: Eric Anholt <eric@anholt.net>

2010-07-26drm/i915: Clear any existing dither mode prior to enabling spatial ditheringChris Wilson
We cannot the initial configuration set by the BIOS not to have a dither mode enabled which conflicts with our enabling the Spatial Temporal 1 dither mode for PCH. In particular, the BIOS may either enable temporal dithering or the Spatial Temporal 2 with the result that we enable pure temporal dithering. Temporal dithering looks bad and is perceived as a flicker.
