[PATCH v4 2/3] drm/bridge: tfp410: Fix logic to configured polled HPD

[Jonathan Cormier]

From: Michael Williamson <michael.william...@criticallink.com>

The logic to configure polling (vs async/irq notification) of hot-plug
events was not correct.  If the connected bridge requires polling,
then inform the upstream bridge we also require polling.

Fixes: 5cafa0f1853b ("drm/bridge: tfp410: Replace manual connector handling 
with bridge")
