drm/vmwgfx: Use a per-device semaphore for reservation protection
Don't use a per-master semaphore (ttm lock) for reservation protection, but rather a per-device semaphore. This is needed since clients connecting using render nodes aren't master aware. The ttm lock used should probably be replaced with a reader-write semaphore once the function down_xx_interruptible() is available. Signed-off-by:Thomas Hellstrom <thellstrom@vmware.com> Reviewed-by:
