From: "Yipeng Chen (Jasber)" <yipeng.chen@xxxxxxx>
[Why]
Enabled ABM (level != 0) would raise short pluse irq DC_IRQ_SOURCE_HPD1RX
randomly with PSR error LINK_CRC_ERROR. Actually there is no hot plugging
on EDP panel. After correcting CRC error, there is no need to send drm
hotplug event.
[How]
Returning false would skip doing hot-plug when handle_hpd_irq_psr_sink()
handled irq. Hot-plug process causes visible flicking on overlay.
