[PATCH 5.4 089/183] drm/tegra: dsi: Fix missing pm_runtime_disable() in the error handling path of tegra_dsi_probe()

From: Sasha Levin
Date: Mon Mar 25 2024 - 01:21:46 EST


From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit 5286a9fc280c45b6b307ee1b07f7a997e042252c ]

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