2012-02-09drm: Fix authentication kernel crashThomas Hellstrom
commit 598781d71119827b454fd75d46f84755bca6f0c6 upstream. If the master tries to authenticate a client using drm_authmagic and that client has already closed its drm file descriptor, either wilfully or because it was terminated, the call to drm_authmagic will dereference a stale pointer into kmalloc'ed memory and corrupt it. Typically this results in a hard system hang. This patch fixes that problem by removing any authentication tokens (struct drm_magic_entry) open for a file descriptor when that file descriptor is closed.

commit ba68e086223a5f149f37bf8692c8cdbf1b0ba3ef upstream. This is a revert of 81a14b46846fea0741902e8d8dfcc6c6c78154c8. We already set the mode polarity using the SDVO commands with struct intel_sdvo_dtd. We have at least 3 bugs that get fixed with this patch. The documentation, despite not clear, can also be interpreted in a way that suggests this patch is needed.

2012-02-08vmwgfx: Fix assignment in vmw_framebuffer_create_handleRyan Mallon
commit bf9c05d5b6d19b3e4c9fe21047694e94f48db89b upstream. The assignment of handle in vmw_framebuffer_create_handle doesn't actually do anything useful and is incorrectly assigning an integer value to a pointer argument. It appears that this is a typo and should be dereferencing handle rather than assigning to it directly. This fixes a bug where an undefined handle value is potentially returned to user-space.

commit f64964796dedca340608fb1075ab6baad5625851 upstream. Avoid infinite loops waiting for surface updates if a GPU reset happens while waiting for a page flip.

2011-12-09drm/radeon/kms: fix up gpio i2c mask bits for r4xxAlex Deucher
commit 6c47e5c23aa2a7c54ad7ac13af4bd56cd9e703bf upstream. Fixes i2c test failures when i2c_algo_bit.bit_test=1. The hw doesn't actually require a mask, so just set it to the default mask bits for r1xx-r4xx radeon ddc.

2011-12-09drm/i915: Fix inconsistent backlight level during disabledTakashi Iwai
commit 04b38670cf46c096705f24e92a8747d1ab89e53c upstream. When the brightness property is inquired while the backlight is disabled, the driver returns a wrong value (zero) because it probes the value after the backlight was turned off. This caused a black screen even after the backlight is enabled again. It should return the internal backlight_level instead, so that it won't be influenced by the backlight-enable state.

commit 9ca1d10d748e56964de95e3ed80211b192f56cf4 upstream. Unlike the previous one, I don't have known testcases it fixes.
