[PATCH] drm: take global drm mutex around sysfs files

This prevents a race between module init and sysfs access (usually only seen at module reload time, or if somehow your userspace starts fast enough and pokes at /sys/class/drm while the drivers are still initializing). Signed-off-by: Jesse Barnes --- drivers/gpu/drm/drm_sysfs.c | 75 ++

[PATCH] drm/i915: Fix single msg gmbus_xfers writes

gmbus_xfer with a single message (particularly a single message write) would set Bus Cycle Select to 100b, the Gen Stop cycle, instead of 101b, No Index, Stop cycle. This would not start single message i2c transactions. Also, gmbus_xfer done: will disable the interface without checking if it is id

[PATCH] drm/i915: Fix race condition in accessing GMBUS

GMBUS has several ports and each has it's own corresponding I2C adpater. When multiple I2C adapters call gmbus_xfer() at the same time there is a race condition in using the underlying GMBUS controller. Fixing this by adding a mutex lock when calling gmbus_xfer(). Signed-off-by: Yufeng Shen ---
