[PATCH 6.7 394/713] drm/tegra: rgb: Fix some error handling paths in tegra_dc_rgb_probe()

[Sasha Levin <sashal@xxxxxxxxxx>]

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit bc456b5d93dbfdbd89f2a036f4f3d8026595f9e4 ]

If an error occurs after calling tegra_output_probe(),
tegra_output_remove() should be called as already done in the remove
function.

Fixes: 59d29c0ec93f ("drm/tegra: Allocate resources at probe time")
