[PATCH] drm: bridge: dw-hdmi: Avoid resetting force in the detect function

2020-11-01 Thread Jonathan Liu
It has been observed that resetting force in the detect function can result in the PHY being powered down in response to hot-plug detect being asserted, even when the HDMI connector is forced on. Enabling debug messages and adding a call to dump_stack() in dw_hdmi_phy_power_off() shows the
