From: Hans de Goede
commit aee6f25e9c911323aa89a200e1bb160c1613ed3d upstream.
After the recently added commit fe0f1e3bfdfe ("drm/i915: Shut down
displays gracefully on reboot"), the DSI panel on a Cherry Trail based
Predia Basic tablet would no longer properly light up after reb
).
This leads to allocating no DDB for the Y plane since .min_ddb_alloc
also gets zeroed. And that of course leads to underruns when scanning
out planar formats.

intel_atomic_crtc_state_for_each_plane_state()

the issue on ThinkPad X1 Titanium Gen1 [1].
I suspect reverting 98e497e203a5 ("drm/i915/dpcd_bl: uncheck PWM_PIN_CAP
when detect eDP backlight capabilities") would too. But then that would
break *other* machines that claim support for *both* eDP PWM pin and
DPCD backlight control
tasklet_unlock_spin_wait() instead which can be invoked from
non-preemptible contexts.

, the guest driver won't detect a valid HPD pulse thus no full
display detection will be executed to read the updated EDID.
With this patch, the vfio_edid is enabled again on BXT/APL, which is
previously disabled.
Fixes: 642403e3599e ("drm/i915/gvt: Temporarily disable vfio_edid for BXT/APL")
might evaluate actual display hotplug for BDW to make this function
work as expected, anyway this is always required to be fixed first.
