Subject: drm/bridge: ti-sn65dsi86: Simplify using pm_runtime_resume_and_get()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c9d99c73940e47692fa982cf7508581f5c55e363;p=linux.git

drm/bridge: ti-sn65dsi86: Simplify using pm_runtime_resume_and_get()

pm_runtime_resume_and_get() already drops the runtime PM usage counter
in the error case. So a call to pm_runtime_put_sync() can be dropped.
