[Intel-gfx] [PATCH v4 0/3] drm/i915/display: stop HPD workers before display driver unregister

[Andrzej Hajda]

Hi Jani, Ville, Arun,

This patchset is replacement of patch
"drm/i915/display: disable HPD workers before display driver unregister" [1].
Ive decided to split patch into two parts - fbdev and MST, there are different
issues.
Ive also dropped shutdown path, as it has slightly different requirements,
and more importantly I am not able to test properly.

v2 (thx Arun for review):
  - reword of commit message (Arun)
  - intel_fbdev_hpd_set_suspend replaced with intel_fbdev_set_suspend (Arun)
v3:
  - new patch adding suspended flag, to handle
    https://gitlab.freedesktop.org/drm/intel/-/issues/5950
v4:
 - check suspend flag also in i915_digport_work_func

Regards
Andrzej
