2016-04-22coresight: add remote etm driver support in upstream implementationShashank Mittal
Add remote etm driver in upstream implementation of Coresight driver. This change copies coresight-remote-etm.c file from drivers/coresight (commit c1fe9ac38d93 ("input: touchscreen: correct function and variable names in ITE tech driver")) to driver/hwtracing/coresight directory.

2016-04-22msm_bus: coresight: fix to support upstream implementationShashank Mittal
Upstream's Coresight driver doesn't have id field in coresight_platform_data. So use device name instead to link bus clk with Coresight device node. Change-Id: I9f70974d64154217c2701879eb428beef1857fcf Signed-off-by: Shashank Mittal <mittals@codeaurora.org>

2016-04-22msm: thermal: Request INT_MAX as max for regulator set voltage APIManaf Meethalavalappu Pallikunhi
During Vdd restriction trigger/clear request, KTM request it's vote to regulator via regulator_set_voltage() API. KTM is interested only in min value for this feature, always request INT_MAX as max value instead of supported MAX corner of that regulator. It makes sure that there is no impact if MAX corner for that regulator is changed at any time.

Depending on the timing of two competing transport registration with G-Link core, a channel gets opened on one transport and then immediately migrated to another transport. This channel migration happens in the context of glink_open() operation itself and causes a re-lock attempt on an already locked mutex.

2016-04-22msm: camera: isp: Set vfe clock rateShubhraprakash Das
Set the initial vfe clock rate to SVS during probe. When the clock is enabled the clock driver expects a clock rate to be voted. The clock is enabled during device open and the user driver can send the actual rate only after open. This causes a warning print from clock driver when the clock is enabled in device open. To avoid the error print set an initail rate. CRs-Fixed: 1000316 Change-Id: I423469eef79fc9251bab52ea3a3b3c9d8db422a3 Signed-off-by: Shubhraprakash Das <sadas@codeaurora.org>

2016-04-22Revert "kernel: lib: allow larger stack frame size for KASan"Satya Durga Srinivasu Prabhala
This reverts commit 8bb334401c84 ("kernel: lib: allow larger stack frame size for KASan"). Stack frame size set to 5600 to fix compilation error/s if KASAN enabled by the commit 8bb334401c84 ("kernel: lib: allow larger stack frame size for KASan") in 3.18 Kernel and same commit got pulled into Kernel 4.4, which replaced stack frame size 0 with 5600 as part of resolution of merge conflict. But, by setting stack frame size to 0 will ignore stack frame size warnings and so the compilation errors. So, revert commit to fix below error while compiling Kernel 4.4 with KASAN enabled and GCC 5.1 compiler. kernel/net/wireless/nl80211.c: In function 'nl80211_send_wiphy': kernel/net/wireless/nl80211.c:1745:1: warning: the frame size of \ 5760 bytes is larger than 5600 bytes [-Wframe-larger-than=] error, forbidden warning: nl80211.c:1745 make[4]: *** [net/wireless/nl80211.o] Error 1 CRs-Fixed: 1004225 Change-Id: I97e52302197c9933bec5cac3ebdc4ec73fee0816 Signed-off-by: Satya Durga Srinivasu Prabhala <satyap@codeaurora.org>

2016-04-20clk: Update clk_get_sys to return ENOENT on failureDevesh Jhunjhunwala
clk_get_sys was updated to return EPROBE_DEFER because on the older kernel returning ENOENT was causing drivers that probed before the clock provider to fail instead of deferring. The new kernel version fixes this by returning EPROBE_DEFER in __of_clk_get_from_provider. Thus, clk_get_sys failing means that the clock provider exists, but the requested clock is not defined in the provider, in which case ENOENT is a more appropriate error code to return.
