From 3258bc1f8cc8b2a486f1b893978e96867f99da51 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Fri, 3 Nov 2023 15:14:06 +0200 Subject: [PATCH] drm/bridge: tc358767: Fix return value on error case [ 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.
