      drm/ttm: Fix a theoretical race in ttm_bo_cleanup_refs() · b8e902f2
      Thomas Hellstrom authored
      
      
      In theory, that function could release the lru lock between
      checking for bo on ddestroy list and a successful reserve if the bo
      was already reserved, and the function was called with waiting reserves
      allowed.
      However, all current reservers of a bo on the ddestroy list would
      atomically take the bo off the list after a successful reserve so this
      race should not have been hit, so no need to backport for stable.
      
      This patch also fixes a case found by Maarten Lankhorst where
      ttm_mem_evict_first called with no_wait_gpu would incorrectly
      spin waiting for bo idle if trying to evict a busy buffer that
      also sits on the ddestroy list.

      The ttm_mem_evict_first function could theoretically drop the
      lru lock without retrying if a reservation from off the LRU list
      ended up waiting.
      However, since currently there are no users that could cause a wait
      in that situation so this is not suitable for stable

      drm: platform: Don't initialize driver-private data · a16d4f86
      Thierry Reding authored
      
      
      Platform device drivers usually use the driver-private data for their
      own purposes. Having it overwritten by drm_platform_init() is confusing
      and error-prone.

      drm: fb: cma: Fail gracefully on allocation failure · 02813245
      Thierry Reding authored
      
      
      The drm_gem_cma_create() function never returns NULL but rather an error
      encoded in the return value using the ERR_PTR() macro. Callers therefore
      need to check for errors using the IS_ERR() macro. This change allows
      drivers to handle contiguous DMA allocation failures gracefully.

      Currently if len argument in ext4_trim_fs() is smaller than one block,
      the 'end' variable underflow. Avoid that by returning EINVAL if len is
      smaller than file system block.
