Subject: drm/tegra: sor: Disable runtime PM on probe failure
X-Git-Tag: v5.6-rc1~34^2~2^2~4
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=ad2139cb80a7a9afbfe428d0448d351a84e22ee6;p=linux.git

drm/tegra: sor: Disable runtime PM on probe failure

If the driver fails to probe, make sure to disable runtime PM again.

While at it, make the cleanup code in ->remove() symmetric.
