Subject: drm/tegra: dc: Release PM and RGB output when client's registration fails
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0411ea89a689531e1829fdf8af3747646c02c721;p=openwrt%2Fstaging%2Fblogic.git

drm/tegra: dc: Release PM and RGB output when client's registration fails

Runtime PM and RGB output need to be released when host1x client
registration fails. The releasing is missed in the code, let's correct it.
