2014-01-14[media] drxk: remove the option to load firmware asynchronouslyMauro Carvalho Chehab
The option to load firmware asynchronously were added due to a requirement with a few versions of udev. It turns that this was a bad idea and caused regressions on drxk-based devices. So, we end by only letting the firmware to be loaded syncronously everywhere. So, let's remove the bad code. This patch partially reverts the changeset 8e30783b0b3.

2014-01-14[media] em28xx: push mutex down to extensions on .fini callbackMauro Carvalho Chehab
Avoid circular mutex lock by pushing the dev->lock to the .fini callback on each extension. As em28xx-dvb, em28xx-alsa and em28xx-rc have their own data structures, and don't touch at the common structure during .fini, only em28xx-v4l needs to be locked.

2014-01-14i2c: Re-instate body of i2c_parent_is_i2c_adapter()Stephen Warren
The body of i2c_parent_is_i2c_adapter() is currently guarded by I2C_MUX. It should be CONFIG_I2C_MUX instead. Among potentially other problems, this resulted in i2c_lock_adapter() only locking I2C mux child adapters, and not the parent adapter. In turn, this could allow inter-mingling of mux child selection and I2C transactions, which could result in I2C transactions being directed to the wrong I2C bus, and possibly even switching between busses in the middle of a transaction. One concrete issue caused by this bug was corrupted HDMI EDID reads during boot on the NVIDIA Tegra Seaboard system, although this only became apparent in recent linux-next, when the boot timing was changed just enough to trigger the race condition.

2014-01-14gpu: host1x: Remove unnecessary includeThierry Reding
Nothing from the asm/mach/irq.h header is needed in this file, so there is no need to include it. Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-01-14drm/tegra: Use proper data typeThierry Reding
The last argument to of_get_property() is a pointer to an int, rather than size_t. Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-01-14drm/tegra: Clarify how panel modes override othersThierry Reding
When a panel advertises one or more modes, they are used exclusively. Other methods for obtaining the mode, such as DDC as used for HDMI or binary EDID blobs embedded in the DT, are ignored. The panel drivers should be providing this functionality if they want to expose it as well. Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-01-14drm/tegra: Fix possible CRTC mask for RGB outputsThierry Reding
The mask of possible CRTCs that an output (DRM encoder) can be attached to is relative to the position within the DRM device's list of CRTCs. Deferred probing can cause this to not match the pipe number associated with a CRTC. Use the newly introduced drm_crtc_mask() to compute the mask by looking up the proper index of the given CRTC in the list. Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-01-14drm/i915: Use drm_encoder_crtc_ok()Thierry Reding
The intel_encoder_crtc_ok() is a duplicate of the drm_encoder_crtc_ok() function that used to be only available in the DRM CRTC helpers. It has recently been moved to the core, so the duplicate can now be dropped.

2014-01-14drm: Move drm_encoder_crtc_ok() to coreThierry Reding
Using the new drm_crtc_mask() function, drm_encoder_crtc_ok() can now be written in a significantly shorter way, so it can be moved to a header file and be made static inline. Signed-off-by: Thierry Reding <treding@nvidia.com>
2014-01-14drm: provide a helper for the encoder possible_crtcs maskRussell King
The encoder possible_crtcs mask identifies which CRTCs can be bound to a particular encoder. Each bit from bit 0 defines an index in the list of CRTCs held in the DRM mode_config crtc_list. Rather than having drivers trying to track the position of their CRTCs in the list, expose the code which already exists for calculating the appropriate mask bit for a CRTC.

git://git.linaro.org/people/daniel.lezcano/linux into timers/core Pull clocksource/clockevent updates from Daniel Lezcano: * Axel Lin removed an unused structure defining the ids for the bcm kona driver. * Ezequiel Garcia enabled the timer divider only when the 25MHz timer is not used for the armada 370 XP. * Jingoo Han removed a pointless platform data initialization for the sh_mtu and sh_mtu2. * Laurent Pinchart added the clk_prepare/clk_unprepare for sh_cmt. * Linus Walleij added a useful warning in clk_of when no clocks are found while the old behavior was to silently hang at boot time. * Maxime Ripard added the high speed timer drivers for the Allwinner SoCs (A10, A13, A20). He increased the rating, shared the irq across all available cpus and fixed the clockevent's irq initialization for the sun4i. * Michael Opdenacker removed the usage of the IRQF_DISABLED for the all the timers driver located in drivers/clocksource. * Stephen Boyd switched to sched_clock_register for the arm_global_timer, cadence_ttc, sun4i and orion timers.

2014-01-14x86/apic: Read Error Status Register correctlyRichard Weinberger
Currently we do a read, a dummy write and a final read to fetch the error code. The value from the final read is taken. This is not the recommended way and leads to corrupted/lost ESR values. Intel(c) 64 and IA-32 Architectures Software Developer's Manual, Combined Volumes 1, 2ABC, 3ABC, Section 10.5.3 states: Before attempt to read from the ESR, software should first write to it. (The value written does not affect the values read subsequently; only zero may be written in x2APIC mode.) This write clears any previously logged errors and updates the ESR with any errors detected since the last write to the ESR. This write also rearms the APIC error interrupt triggering mechanism. This patch removes the first read such that we are conform with the manual. On my (very old) Pentium MMX SMP system this patch fixes the issue that APIC errors: a) are not always reported and b) are reported with false error numbers.
