Just one fix this time round to further improve reliability of resets on
execlists platforms in some edge cases.
Not sure if there is scope to do one more fixes pull before 5.19 is out so
just in case. If it doesn't get pulled we'll send it to stable after release.

Hi,
We would like to report the following bug which has been found by our
modified version of syzkaller.
==
description: BUG: unable to handle kernel paging request in imageblit
affected file: drivers/gpu/drm/drm_fb_helper.c
kernel version:
The fbtft_framebuffer_alloc() calls fb_deferred_io_init() before
initializing info->fix.smem_len. It is set to zero by the
framebuffer_alloc() function. It will trigger a WARN_ON() at the
start of fb_deferred_io_init() and the function will not do anything.
Fixes: 856082f021a2 ("fbdev: defio:
Call drm_plane_enable_fb_damage_clips() and give userspace a chance
of minimizing the updated display area.
