5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tomi Valkeinen <tomi.valkeinen@xxxxxxxxxxxxxxxx>
[ Upstream commit 32bd29b619638256c5b75fb021d6d9f12fc4a984 ]
If the hpd_pin is invalid, the driver returns 'ret'. But 'ret' contains
0, instead of an error value.
Return -EINVAL instead.
Fixes: f25ee5017e4f ("drm/bridge: tc358767: add IRQ and HPD support")
