[PATCH 6.1 190/417] drm/bridge: tc358767: Fix return value on error case

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.1-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.
