Subject: [PATCH] drm/bridge: it6505: Fix return value check for pm_runtime_get_sync
Git-commit: 3e4a21a29dd924995f1135cd50e8b7e0d023729c
Patch-mainline: v6.2-rc1
References: git-fixes

`pm_runtime_get_sync` may return 1 on success. Fix the `if` statement
here to make the code less confusing, even though additional calls to
`it6505_poweron` doesn't break anything when it's already powered.
