Subject: Re: [PATCH 022/102] drm/sti: explicitly request exclusive reset control

> Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
> reset lines") started to transition the reset control request API calls
> to explicitly state whether the driver needs exclusive or shared reset
> control behavior. Convert all drivers requesting exclusive resets to the
> explicit API call so the temporary transition helpers can be removed.

> No functional changes.
