gen8_de_irq_postinstall() wasn't masking the IRQ bit before passing the
debug flag to psr_irq_control(). This check was missed when new debug bits
were defined in 'commit c44301fce614 ("drm/i915: Allow control of PSR at
runtime through debugfs, v6")'. Instead of ANDing the irq bit in all the
callers, move it to the callee.
v2: Rebased.
Fixes: c44301fce614 ("drm/i915: Allow control of PSR at runtime through
debugfs, v6")
