2016-02-04[media] lgs8gxx: don't export get_frontend() callbackMauro Carvalho Chehab
This device doesn't really have a get_frontend(). All it does is to blindly set everything to auto mode. Remove the get_frontend(), as the code does that already, and put the frontend changes at set_frontend, where it belongs. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

2016-02-04lightnvm: allow to force mm initializationMatias Bjørling
System block allows the device to initialize with its configured media manager. The system blocks is written to disk, and read again when media manager is determined. For this to work, the backend must store the data. Device drivers, such as null_blk, does not have any backend storage. This patch allows the media manager to be initialized without a storage backend. It also fix incorrect configuration of capabilities in null_blk, as it does not support get/set bad block interface.

2016-02-04ALSA: timer: Fix leftover link at closingTakashi Iwai
In ALSA timer core, the active timer instance is managed in active_list linked list. Each element is added / removed dynamically at timer start, stop and in timer interrupt. The problem is that snd_timer_interrupt() has a thinko and leaves the element in active_list when it's the last opened element. This eventually leads to list corruption or use-after-free error. This hasn't been revealed because we used to delete the list forcibly in snd_timer_stop() in the past. However, the recent fix avoids the double-stop behavior (in commit [f784beb75ce8: ALSA: timer: Fix link corruption due to double start or stop]), and this leak hits reality. This patch fixes the link management in snd_timer_interrupt(). Now it simply unlinks no matter which stream is.

2016-02-04drm/i915/fbc: unexport the HW level activation functionsPaulo Zanoni
The recent introduction of a new caller of dev_priv->fbc.deactivate() is a good example of why we need unexport those functions. Anything outside intel_fbc.c should only call the functions exported by intel_fbc.c, so in order to enforce that, kill the function pointers stored inside dev_priv->fbc and replace them with functions that can't be called from outside intel_fbc.c.

2016-02-04drm/i915: implement WaIncreaseDefaultTLBEntriesTim Gore
WaIncreaseDefaultTLBEntries increases the number of TLB entries available for GPGPU workloads and gives significant ( > 10% ) performance gain for some OCL benchmarks. Put this in a new function that can be a place for workarounds that are GT related but not required per ring. This function is called on driver load and also after a reset and on resume, so it is safe for workarounds that get clobbered in these situations. This function currently has just this one workaround. v2: This was originally split into 3 patches but following review feedback was squashed into 1. I have not incorporated some style comments from Chris Wilson as I felt that after defining and intialising a temporary variable and then adding an additional if block to only write the register if the temporary variable had been set, this didn't really give a net gain. v3: Resending in the hope that BAT will run v4: Change subject line to trigger BAT (please!)

While cleaning resources on module pmd event, we check for return of skl_unbind_modules(). On failure this causes leak as all modules attached do not have resources freed. So ignore return value of module unbind and continue freeing resources. This makes dapm state and resources correct.

2016-02-04ASoC: Intel: Skylake: Fix delay wrap conditionGuneshwor Singh
When delay reported by HW is equal to buffersize, it means the value is wrapped so we should report as 0. So add the condition to check this while reporting the delay from LPIB.

2016-02-04ASoC: Intel: Skylake: Fix the memory overwrite of tlv bufferVinod Koul
TLV buffer can be smaller than the module data, so update the size of data to be copied before doing the copy. Also TLV header consists of two unsigned ints, this is also taken into account here and size modified to reflect this Suggested-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2016-02-04[media] vb2-core: call threadio->fnc() if !VB2_BUF_STATE_ERRORMauro Carvalho Chehab
changeset 70433a152f0 ("media: videobuf2: Refactor vb2_fileio_data and vb2_thread") broke videobuf2-dvb. The root cause is that, instead of calling threadio->fnc() for all types of events except for VB2_BUF_STATE_ERROR, it was calling it only for VB2_BUF_STATE_DONE. With that, the DVB thread were never called. Cc: stable@vger.kernel.org # Kernel >= 4.3 Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2016-02-04[media] vb2: fix nasty vb2_thread regressionHans Verkuil
The vb2_thread implementation was made generic and was moved from videobuf2-v4l2.c to videobuf2-core.c in commit af3bac1a. Unfortunately that clearly was never tested since it broke read() causing NULL address references. The root cause was confused handling of vb2_buffer vs v4l2_buffer (the pb pointer in various core functions). The v4l2_buffer no longer exists after moving the code into the core and it is no longer needed. However, the vb2_thread code passed a pointer to a vb2_buffer to the core functions were a v4l2_buffer pointer was expected and vb2_thread expected that the vb2_buffer fields would be filled in correctly. This is obviously wrong since v4l2_buffer != vb2_buffer. Note that the pb pointer is a void pointer, so no type-checking took place. This patch fixes this problem: 1) allow pb to be NULL for vb2_core_(d)qbuf. The vb2_thread code will use a NULL pointer here since they don't care about v4l2_buffer anyway. 2) let vb2_core_dqbuf pass back the index of the received buffer. This is all vb2_thread needs: this index is the index into the q->bufs array and vb2_thread just gets the vb2_buffer from there. 3) the fileio->b pointer (that originally contained a v4l2_buffer) is removed altogether since it is no longer needed. Tested with vivid and the cobalt driver.

2016-02-04[media] tda1004x: only update the frontend properties if lockedMauro Carvalho Chehab
The tda1004x was updating the properties cache before locking. If the device is not locked, the data at the registers are just random values with no real meaning. This caused the driver to fail with libdvbv5, as such library calls GET_PROPERTY from time to time, in order to return the DVB stats.

2016-02-04ASoC: dapm: Don't prefix autodisable widgets twiceLars-Peter Clausen
When a DAPM context has a prefix the autodisable widgets get prefixed twice, once for the control and once for the widget. To avoid this use the un-prefixed control name to construct the autodisable widget name. This change is purely cosmetic.
