So I wanted to quickly move our struct fb_ops to const data because we
don't modify it... and this series is where the rabbit hole ends. Ugh.
The main pain point is deferred IO, which is covered in patch
1. Everything gets easier after that. The last 5 could be merged at
leisure.
BR,
Jani.
Jani Nikula (13):
video: fb_defio: preserve user fb_ops
drm/fb-helper: don't preserve fb_ops across deferred IO use
video: smscufx: don't restore fb_mmap after deferred IO cleanup
video: udlfb: don't restore fb_mmap after deferred IO cleanup
video: fbdev: vesafb: modify the static fb_ops directly
video: fbmem: use const pointer for fb_ops
video: omapfb: use const pointer for fb_ops
video: fbdev: make fbops member of struct fb_info a const pointer
drm: constify fb ops across all drivers
video: constify fb ops across all drivers
HID: picoLCD: constify fb ops
media: constify fb ops across all drivers
samples: vfio-mdev: constify fb ops
