2014-11-05staging:iio:ad5933: Fix NULL pointer deref when enabling bufferLars-Peter Clausen
In older versions of the IIO framework it was possible to pass a completely different set of channels to iio_buffer_register() as the one that is assigned to the IIO device. Commit 959d2952d124 ("staging:iio: make iio_sw_buffer_preenable much more general.") introduced a restriction that requires that the set of channels that is passed to iio_buffer_register() is a subset of the channels assigned to the IIO device as the IIO core will use the list of channels that is assigned to the device to lookup a channel by scan index in iio_compute_scan_bytes(). If it can not find the channel the function will crash. This patch fixes the issue by making sure that the same set of channels is assigned to the IIO device and passed to iio_buffer_register(). Fixes the follow NULL pointer derefernce kernel crash: Unable to handle kernel NULL pointer dereference at virtual address 00000016 pgd = d53d0000 [00000016] *pgd=1534e831, *pte=00000000, *ppte=00000000 Internal error: Oops: 17 [#1] PREEMPT SMP ARM Modules linked in: CPU: 1 PID: 1626 Comm: bash Not tainted 3.15.0-19969-g2a180eb-dirty #9545 task: d6c124c0 ti: d539a000 task.ti: d539a000 PC is at iio_compute_scan_bytes+0x34/0xa8 LR is at iio_compute_scan_bytes+0x34/0xa8 pc : [<c03052e4>] lr : [<c03052e4>] psr: 60070013 sp : d539beb8 ip : 00000001 fp : 00000000 r10: 00000002 r9 : 00000000 r8 : 00000001 r7 : 00000000 r6 : d6dc8800 r5 : d7571000 r4 : 00000002 r3 : d7571000 r2 : 00000044 r1 : 00000001 r0 : 00000000 Flags: nZCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment user Control: 18c5387d Table: 153d004a DAC: 00000015 Process bash (pid: 1626, stack limit = 0xd539a240) Stack: (0xd539beb8 to 0xd539c000) bea0: c02fc0e4 d7571000 bec0: d76c1640 d6dc8800 d757117c 00000000 d757112c c0305b04 d76c1690 d76c1640 bee0: d7571188 00000002 00000000 d7571000 d539a000 00000000 000dd1c8 c0305d54 bf00: d7571010 0160b868 00000002 c69d3900 d7573278 d7573308 c69d3900 c01ece90 bf20: 00000002 c0103fac c0103f6c d539bf88 00000002 c69d3b00 c69d3b0c c0103468 bf40: 00000000 00000000 d7694a00 00000002 000af408 d539bf88 c000dd84 c00b2f94 bf60: d7694a00 000af408 00000002 d7694a00 d7694a00 00000002 000af408 c000dd84 bf80: 00000000 c00b32d0 00000000 00000000 00000002 b6f1aa78 00000002 000af408 bfa0: 00000004 c000dc00 b6f1aa78 00000002 00000001 000af408 00000002 00000000 bfc0: b6f1aa78 00000002 000af408 00000004 be806a4c 000a6094 00000000 000dd1c8 bfe0: 00000000 be8069cc b6e8ab77 b6ec125c 40070010 00000001 22940489 154a5007 [<c03052e4>] (iio_compute_scan_bytes) from [<c0305b04>] (__iio_update_buffers+0x248/0x438) [<c0305b04>] (__iio_update_buffers) from [<c0305d54>] (iio_buffer_store_enable+0x60/0x7c) [<c0305d54>] (iio_buffer_store_enable) from [<c01ece90>] (dev_attr_store+0x18/0x24) [<c01ece90>] (dev_attr_store) from [<c0103fac>] (sysfs_kf_write+0x40/0x4c) [<c0103fac>] (sysfs_kf_write) from [<c0103468>] (kernfs_fop_write+0x110/0x154) [<c0103468>] (kernfs_fop_write) from [<c00b2f94>] (vfs_write+0xd0/0x160) [<c00b2f94>] (vfs_write) from [<c00b32d0>] (SyS_write+0x40/0x78) [<c00b32d0>] (SyS_write) from [<c000dc00>] (ret_fast_syscall+0x0/0x30) Code: ea00000e e1a01008 e1a00005 ebfff6fc (e5d0a016) Fixes: 959d2952d124 ("staging:iio: make iio_sw_buffer_preenable much more general.")

When a device has both audio and midi interfaces, it gets called twice, and currently the driver tries to release resources at the last call. At this point, the first parent interface has been already deleted, thus deleting a child of the first parent hits such a warning. For fixing this problem, we need to call snd_card_disconnect() and cancel pending operations at the very first disconnect while the release of the whole objects waits until the last disconnect call.

2014-11-05KVM: x86: Fix uninitialized op->type for some immediate valuesNadav Amit
The emulator could reuse an op->type from a previous instruction for some immediate values. If it mistakenly considers the operands as memory operands, it will performs a memory read and overwrite op->val. Consider for instance the ROR instruction - src2 (the number of times) would be read from memory instead of being used as immediate. Mark every immediate operand as such to avoid this problem.

2014-11-05mmc: core: fix card detection regressionKristina Martsenko
Since commit 89168b489915 ("mmc: core: restore detect line inversion semantics"), the SD card on i.MX28 (and possibly other) devices isn't detected and booting stops at: [ 4.120617] Waiting for root device /dev/mmcblk0p3... This is caused by the MMC_CAP2_CD_ACTIVE_HIGH flag being set incorrectly when the host controller doesn't use a GPIO for card detection (but instead uses a dedicated pin). In this case mmc_gpiod_request_cd() will return before assigning to the gpio_invert variable, leaving the variable uninitialized. The variable then gets used to set the flag. This patch fixes the issue by making sure gpio_invert is set to false when a GPIO isn't used. After this patch, i.MX28 boots fine. The MMC_CAP2_RO_ACTIVE_HIGH (write protect) flag is also set incorrectly for the exact same reason (it uses the same uninitialized variable), so this patch fixes that too.

Because percpu_ref killing and draining involve a RCU grace period, doing the above on one queue after another may take a long time if there are many queues on the system. This patch splits out initiation of freezing and waiting for its completion, and updates blk_mq_queue_reinit_notify() so that the queues are frozen in parallel instead of one after another. Note that freezing and unfreezing are moved from blk_mq_queue_reinit() to blk_mq_queue_reinit_notify().

2014-11-04of: Fix overflow bug in string property parsing functionsGrant Likely
The string property read helpers will run off the end of the buffer if it is handed a malformed string property. Rework the parsers to make sure that doesn't happen. At the same time add new test cases to make sure the functions behave themselves. The original implementations of of_property_read_string_index() and of_property_count_strings() both open-coded the same block of parsing code, each with it's own subtly different bugs. The fix here merges functions into a single helper and makes the original functions static inline wrappers around the helper. One non-bugfix aspect of this patch is the addition of a new wrapper, of_property_read_string_array(). The new wrapper is needed by the device_properties feature that Rafael is working on and planning to merge for v3.19. The implementation is identical both with and without the new static inline wrapper, so it just got left in to reduce the churn on the header file.

2014-11-04ARM: imx: clk-vf610: define PLL's clock treeStefan Agner
So far, the required PLL's (PLL1/PLL2/PLL5) have been initialized by boot loader and the kernel code defined fixed rates according to those default configurations. Beginning with the USB PLL7 the code started to initialize the PLL's itself (using imx_clk_pllv3). However, since commit dc4805c2e78ba5a22ea1632f3e3e4ee601a1743b (ARM: imx: remove ENABLE and BYPASS bits from clk-pllv3 driver) imx_clk_pllv3 no longer takes care of the ENABLE and BYPASS bits, hence the USB PLL were not configured correctly anymore. This patch not only fixes those USB PLL's, but also makes use of the imx_clk_pllv3 for all PLL's and alignes the code with the PLL support of the i.MX6 series.

2014-11-03usb: core: notify disconnection when core detects disconnectPeter Chen
It is safe to call notify disconnect when the usb core thinks the device is disconnected. This commit also fixes one bug found at below situation: we have not enabled usb wakeup, we do system suspend when there is an usb device at the port, after suspend, we plug out the usb device, then plug in device again. At that time, the nofity disconnect was not called at current code, as the controller doesn't know the usb device was disconnected during the suspend, but USB core knows the port has changed during that periods. So to fix this problem, and let the usb core call notify disconnect.

2014-11-03xhci: Disable streams on Asmedia 1042 xhci controllersHans de Goede
Streams seem to be broken on the Asmedia 1042. An uas capable Seagate disk which is known to work fine with other controllers causes the system to freeze when connected over usb-3 with this controller, where as it works fine with uas in usb-2 ports, indicating a problem with streams. This is a bit bigger hammer then I would like to use for this, but for now it will have to make do. I've ordered a pci-e usb controller card with an Asmedia 1042, once that arrives I'll try to get streams to work (with a quirk flag if necessary) and then we can re-enable them. For now this at least makes uas capable disk enclosures work again by forcing fallback to the usb-storage driver.
