[PATCH v2 0/2] fix missing unplug interrupt problem

From: Kuogee Hsieh
Date: Wed Jan 13 2021 - 14:01:53 EST


Both AUX_SW_RESET and DP_SW_RESET clear pending HPD interrupts.
Therefore irq_hpd handler should not issues either aux or sw reset
to avoid following unplug interrupt be cleared accidentally.
