The video encode/decode paths have duplicated logic between VIDIOC_TRY_FMT and VIDIOC_S_FMT that should be de-duped. Also, video decode reports V4L2_PIX_FMT_NV12MT_16X16 output format, regardless of what the actual output has been set at. Fix this.

2013-09-03gpio: improve error path in gpiolibLinus Walleij1-16/+25
At several places the gpiolib will proceed to handle a GPIO descriptor even if it's ->chip member is NULL and no gpiochip is associated. Fix this by checking that both the descriptor cookie *and* the chip pointer are valid. Also bail out earlier with more specific diagnostic messages on missing operations for setting as input/output or debounce. ChangeLog v1->v2: - Also return -EIO on gpiod_set_debounce() with missing operations in the vtable - Fix indentations.

2013-09-03pwm: pxa: Use module_platform_driverMike Dunn1-11/+1
Commit 76abbdde2d95a3807d0dc6bf9f84d03d0dbd4f3d pwm: Add sysfs interface causes a kernel oops due to a null pointer dereference on PXA platforms. This happens because the class added by the patch is registered in a subsys_initcall (initcall4), but the pxa pwm driver is registered in arch_initcall (initcall3). If the class is not registered before the driver probe function runs, the oops occurs in device_add() when the uninitialized pointers in struct class are dereferenced. I don't see a reason that the driver must be an arch_initcall, so this patch makes it a regular module_platform_driver (initcall6), preventing the oops.

2013-09-03drm/i915: fix lvds/dp panel fitter settingImre Deak1-0/+2
If need to enable the panel fitter, the crtc timings have to be programmed according to the panel's native (fixed) mode. This isn't the case atm, since after the encoder changes adjusted_mode to fixed mode the crtc_* timing fields of adjusted_mode will stay at their original non-native values that the user passed in. This results in a corrupted output. One exception is when we have a second pass of computing encoder configs due to bandwidth limitation, since then we'll set adjusted_mode.crtc_* fields to the fixed mode values set in the first pass; so in this case things will work out. Fix this by updating the adjusted_mode.crtc_* fields when we set the fixed panel mode.

2013-09-03drm/i915: Don't mask EI UP interrupt on IVB|SNBMika Kuoppala1-1/+11
Submitting a batchbuffer which simulates a gpu hang by doing MI_BATCH_BUFFER_START into itself, to test hangcheck, started to hard hang the whole box (IVB). Bisecting lead to this commit: commit 664b422c2966cd39b8f67e8d53a566ea8c877cd6 Author: Vinit Azad <[email protected]> Date: Wed Aug 14 13:34:33 2013 -0700 drm/i915: Only unmask required PM interrupts Experimenting with the mask register showed that unmasking EI UP will prevent the hard hang in IVB and SNB. HSW doesn't hang with EI UP masked. Considering we are just disabling interrupts that aren't even delivered to driver, this change is more likely to paper over some weirdness in gpu's internal state machine. But until better explanation can be found, let's trade little bit of power for stability on these architectures. v2: - Unmask EI_EXPIRED directly in I915_WRITE (Vinit) v3: - Only unmask on SNB and IVB Cc: Vinit Azad <[email protected]> Signed-off-by: Mika Kuoppala <[email protected]> Acked-by: Vinit Azad <[email protected]> Signed-off-by: Daniel Vetter <[email protected]>

2013-09-02RDMA/ocrdma: Dont use PD 0 for userpace CQ DBNaresh Gottumukkala6-40/+339
Create_CQ verb doesn't provide a PD pointer. So, until now we are creating all (both userspace and kernel) CQ DB regions from PD0. This will result in mmapping PD0 to applications. A rogue userspace application can mess things up. Also more serious issues is even the be2net NIC uses PD0. This patch addresses this problem by: 1) Create a PD page for every userspace application when the alloc_ucontext is called. This will be destroyed in dealloc_ucontext. 2) All CQs for that context will use the PD allocated in ucontext. 3) The first create_PD call from application will result in returning the PD address from its ucontext (no new PD will be created). 4) For subsecquent create_pd calls from application, we create new PDs for the application.
