Subject: drm/xe/display: Add missing HPD interrupt enabling during non-d3cold RPM resume
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=bbc4a30de095f0349d3c278500345a1b620d495e;p=users%2Fjedix%2Flinux-maple.git

drm/xe/display: Add missing HPD interrupt enabling during non-d3cold RPM resume

Atm the display HPD interrupts that got disabled during runtime
suspend, are re-enabled only if d3cold is enabled. Fix things by
also re-enabling the interrupts if d3cold is disabled.
