Subject: [Intel-gfx] [PATCH] drm/i915/display: Fix mode private_flags comparison at atomic_check
Date: Thu, 26 Mar 2020 13:19:28 +0530 [thread overview]
Message-ID: <20200326074928.10395-1-uma.shankar@intel.com> (raw)
This patch fixes the private_flags of mode to be checked and
compared against uapi.mode and not from hw.mode. This helps
properly trigger modeset at boot if desired by driver.
It helps resolve audio_codec initialization issues if display
is connected at boot. Initial discussion on this issue has happened
on below thread:
