2016-06-22pinctrl: single: Fix missing flush of posted write for a wakeirqTony Lindgren
With many repeated suspend resume cycles, the pin specific wakeirq may not always work on omaps. This is because the write to enable the pin interrupt may not have reached the device over the interconnect before suspend happens. Let's fix the issue with a flush of posted write with a readback.

2016-06-22PM / devfreq: fix initialization of current frequency in last statusLukasz Luba
Some systems need current frequency from last_status for calculation but it is zeroed during initialization. When the device starts there is no history, but we can assume that the last frequency was the same as the initial frequency (which is also used in 'previous_freq'). The log shows the result of this misinterpreted value. [ 2.042847] ...

2016-06-22ACPICA: Namespace: Fix deadlock triggered by MLC support in dynamic table ↵Lv Zheng
loading The new module-level code (MLC) approach invokes MLC on the per-table basis, but the dynamic loading support of this is incorrect because of the lock order: acpi_ns_evaluate acpi_ex_enter_intperter acpi_ns_load_table (triggered by Load opcode) acpi_ns_exec_module_code_list acpi_ex_enter_intperter The regression is introduced by the following commit: Commit: 2785ce8d0da1cac9d8f78615e116cf929e9a9123 ACPICA Commit: 071eff738c59eda1792ac24b3b688b61691d7e7c Subject: ACPICA: Add per-table execution of module-level code This patch fixes this regression by unlocking the interpreter lock before invoking MLC. However, the unlocking is done to the acpi_ns_load_table(), in which the interpreter lock should be locked by acpi_ns_parse_table() but it wasn't.

2016-06-21drm/i915/fbc: Disable on HSW by default for nowLyude
>From https://bugs.freedesktop.org/show_bug.cgi?id=96461 : This was kind of a difficult bug to track down. If you're using a Haswell system running GNOME and you have fbc completely enabled and working, playing videos can result in video artifacts. Steps to reproduce: - Run GNOME - Ensure FBC is enabled and active - Download a movie, I used the ogg version of Big Buck Bunny for this - Run `gst-launch-1.0 filesrc location='some_movie.ogg' ! decodebin ! glimagesink` in a terminal - Watch for about over a minute, you'll see small horizontal lines go down the screen. For the time being, disable FBC for Haswell by default. Stefan Richter reported kernel freezes (no video artifacts) when fbc is on. (E3-1245 v3 with HD P4600; openbox and some KDE and LXDE applications, thread begins at https://lkml.org/lkml/2016/4/26/813).

2016-06-19drm/exynos: fimd: don't set .has_hw_trigger in s3c6400 driver dataJavier Martinez Canillas
The field value is only checked in fimd_setup_trigger() if .trg_type is I80_HW_TRG so there's no point in setting this field for the s3c6400 if is never going to be used since .trg_type is not set.

2016-06-19drm/exynos: dp: Fix NULL pointer dereference due uninitialized connectorYakir Yang
Commit 3424e3a4f844 ("drm: bridge: analogix/dp: split exynos dp driver to bridge directory") split the Exynos DP core driver into a core driver and a bridge driver for the Analogix chip since that is also used by Rockchip. But the change introduced a regression causing a NULL pointer dereference when trying to access an uninitialized connector in the driver .get_modes: Fix this by instead of having a connector struct for both the Exynos and Analogix drivers, just use the connector initialized in the bridge driver.

2016-06-18hwmon: (dell-smm) Disallow fan_type() calls on broken machinesPali Rohár
Some Dell machines have especially broken SMM or BIOS which cause that once fan_type() is called then CPU fan speed going randomly up and down. And for fixing this behaviour reboot is required. So this patch creates fan_type blacklist of affected Dell machines and disallow fan_type() call on them to prevent that erratic behaviour. Old blacklist which disabled loading driver on some machines added in commits a4b45b25f18d ("hwmon: (dell-smm) Blacklist Dell Studio XPS 8100") and 6220f4ebd7b4 ("hwmon: (dell-smm) Blacklist Dell Studio XPS 8000") were moved to FAN_TYPE blacklist.
