[PATCH v7 6/7] drm/msm/dp: delete EV_HPD_INIT_SETUP

From: Kuogee Hsieh
Date: Fri Oct 06 2023 - 18:55:49 EST


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 became obsolete.
msm_dp_irq_postinstall() which triggers EV_HPD_INIT_SETUP event is
obsoleted accordingly.

Changes in v4:
-- reworded commit text
-- drop EV_HPD_INIT_SETUP
-- drop msm_dp_irq_postinstall()

Changes in v3:
-- drop EV_HPD_INIT_SETUP and msm_dp_irq_postinstall()
