Subject: drm/i915/psr: Fixes for Dell XPS DA14260 quirk
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=1de647abdfda9dc307503d0a85152161850ba52c;p=thirdparty%2Flinux.git

drm/i915/psr: Fixes for Dell XPS DA14260 quirk

Dell seems to be changing device ID even within same device model. Due to
this we need to ignore device ID when applying quirk for Dell XPS 14
DA14260. Do this by adding DEVICE_ID_ANY and assign it to Dell XPS 14
DA14260 quirk. Also apply the quirk only for eDP Panel Replay.

Fixes: 45c77d4bf8d4 ("drm/i915/psr: Disable Panel Replay on Dell XPS 14 DA14260 as a quirk")
