Hello, This patch series contains two fixes and a cleanup for things that I noticed while debugging a regression in the fbdev emulation for a DRM driver. 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 Javier Martinez Canillas (3): fbdev: Remove unused struct fb_deferred_io .first_io field drm/fb-helper: Check fb_deferred_io_init() return value drm/fb-helper: Use a per-driver FB deferred I/O handler drivers/gpu/drm/drm_fbdev_generic.c | 15 ++++++++------- drivers/video/fbdev/core/fb_defio.c | 4 ---- include/drm/drm_fb_helper.h | 10 ++++++++++ include/linux/fb.h | 1 - 4 files changed, 18 insertions(+), 12 deletions(-) -- 2.39.0
