From: Thierry Reding Date: Fri, 31 Jan 2020 16:59:09 +0000 (+0100) Subject: drm/tegra: sor: Disable runtime PM on probe failure X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ad2139cb80a7a9afbfe428d0448d351a84e22ee6;p=openwrt%2Fstaging%2Fblogic.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.
