2013-05-23Return the result from user admin command IOCTL even in case of failureChayan Biswas
We copy the result to user if the command is completed from the controller even if it completes with failure (non-zero) status. A return status of < 0 indicates the command was not completed by the controller. The user application may expect the error code in the result field in case of failure.

2013-05-23regmap: regcache: Fixup locking for custom lock callbacksLars-Peter Clausen
The parameter passed to the regmap lock/unlock callbacks needs to be map->lock_arg, regcache passes just map. This works fine in the case that no custom locking callbacks are used since in this case map->lock_arg equals map, but will break when custom locking callbacks are used. The issue was introduced in commit 0d4529c5("regmap: make lock/unlock functions customizable") and is fixed by this patch.

2013-05-23OMAPDSS: Fix crash with DT bootTomi Valkeinen
When booting with DT, there's a crash when omapfb is probed. This is caused by the fact that omapdss+DT is not yet supported, and thus omapdss is not probed at all. On the other hand, omapfb is always probed. When omapfb tries to use omapdss, there's a NULL pointer dereference crash. The same error should most likely happen with omapdrm and omap_vout also. To fix this, add an "initialized" state to omapdss. When omapdss has been probed, it's marked as initialized. omapfb, omapdrm and omap_vout check this state when they are probed to see that omapdss is actually there.

2013-05-22tg3: Ensure boot code has completed initialization before accessing hardwareNithin Sujir
After resetting the device, the driver waits for a signature to be updated to know that firmware has completed initialization. However, the call to tg3_poll_fw() is being done too late and we're writing to the GRC_MODE register before it has completely initialized, causing contention with firmware. This logic has existed since day one but is causing PCIE link to go down randomly at startup on one platform once every few hundred reboots. Move the tg3_poll_fw() up to before we write to the GRC_MODE register after reset.

2013-05-22ath9k: prevent aggregation session deadlocksFelix Fietkau
Waiting for all subframes of an existing aggregation session to drain before allowing mac80211 to start a new one is fragile and deadlocks caused by this behavior have been observed. Since mac80211 has proper synchronization for aggregation session start/stop handling, a better approach to session handling is to simply allow mac80211 to start a new session at any time. This requires changing the code to discard any packets outside of the BlockAck window in the A-MPDU software retry code. This patch implements the above and also simplifies the code.

2013-05-22drm/i915: avoid premature DP AUX timeoutsImre Deak
During DP AUX communication we might time out 1 jiffy too early, because the calculated expiry jiffy value is one less than needed. This is only one reason for false DP AUX timeouts. For a complete solution we also need the following fix, which is now queued for mainline: http://marc.info/?l=linux-kernel&m=136748515710837&w=2 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=64133 Signed-off-by: Imre Deak <imre.deak@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2013-05-22drm/i915: avoid premature timeouts in __wait_seqno()Imre Deak
At the moment wait_event_timeout/wait_event_interruptible_timeout may time out 1 jiffy too early, as the calculated expiry time is 1 less than needed. Besides timing out too early this also means that the calculation of the remaining time will be incorrect and we will pass a non-zero remaining time to user space in case of a time out.

2013-05-22drm/i915: add msecs_to_jiffies_timeout to guarantee minimum durationImre Deak
We need this to avoid premature timeouts whenever scheduling a timeout based on the current jiffies value. For an explanation see [1]. The following patches will take the helper into use. Once the more generic solution proposed in the thread at [1] is accepted this patch can be reverted while keeping the follow-up patches.

2013-05-22cpufreq: arm_big_little_dt: Instantiate as platform_driverViresh Kumar
As multiplatform build is being adopted by more and more ARM platforms, initcall function should be used very carefully. For example, when both arm_big_little_dt and cpufreq-cpu0 drivers are compiled in, arm_big_little_dt driver may try to register even if we had platform device for cpufreq-cpu0 registered. To eliminate this undesired the effect, the patch changes arm_big_little_dt driver to have it instantiated as a platform_driver. Then it will only run on platforms that create the platform_device "arm-bL-cpufreq-dt".

2013-05-22cpufreq: arm_big_little_dt: Register driver only if DT has valid dataViresh Kumar
If arm_big_little_dt driver is enabled, then it will always try to register with big LITTLE cpufreq core driver. In case DT doesn't have relevant data for cpu nodes, i.e. operating points aren't present, then we should exit early and shouldn't register with big LITTLE cpufreq core driver. Otherwise we will fail continuously from the driver->init() routine. This patch fixes this issue.
