The first two patches are trivial and shoulnd't be controversial, the third patch is less trivial, but it has been already reviewed by Thomas and I did test it to make sure that works as expected. With it, I got rid of the WARN that happened due a mutex used after it has been destroyed. Best regards, Javier Changes in v2: - Re-introduce the CONFIG_FB_DEFERRED_IO ifdef guard for the @fbdefio field declaration since the kernel test robot reported that's needed at the end.
