--- Comment #1 from Dhinakaran Pandiyan <dhinakaran.pandiyan at intel.com> ---
With the below patch, this should now be a test assertion failure instead of
dmesg-fail

drm/i915/psr: Remove wait_for_idle() for PSR2
CI runs show PSR2 does not go to IDLE with selective update enabled on
all PSR exit triggers. Specifically, logs indicate the hardware enters
"SLEEP Selective Update" and not "IDLE Reset state', like the kernel
expects, when vblank interrupts are enabled. This check was added for PSR1
but incorrectly extended to PSR2, remove the check as it breaks tests
and prints out misleading error messages.

v2: Split out non-code changes (Rodrigo)
