Subject: [PATCH v1 3/5] drm/msm/dp: delete EV_HPD_INIT_SETUP
Date:   Fri, 7 Jul 2023 16:52:21 -0700
Message-ID: <1688773943-3887-4-git-send-email-quic_khsieh@quicinc.com>
In-Reply-To: <1688773943-3887-1-git-send-email-quic_khsieh@quicinc.com>

EV_HPD_INIT_SETUP flag is used to trigger the initialization of external
DP host controller. Since external DP host controller initialization had
been incorporated into pm_runtime_resume(), this flag become obsolete.
Lets get rid of it.
