[PATCH 0/3] fbdev: stop using compat_alloc_user_space

From: Arnd Bergmann
Date: Fri Sep 18 2020 - 06:08:52 EST

The fbdev code uses compat_alloc_user_space in a few of its
compat_ioctl handlers, which tends to be a bit more complicated
and error-prone than calling the underlying handlers directly,
so I would like to remove it completely.

This modifies two such functions in fbdev, and removes another
one that is completely unused.


Arnd Bergmann (3):
fbdev: simplify fb_getput_cmap()
fbdev: sbuslib: remove unused FBIOSCURSOR32 helper
fbdev: sbuslib: remove compat_alloc_user_space usage
