Subject: [PATCH v4 17/20] drm/amd: cleanup: drm_modeset_lock_all() --> DRM_MODESET_LOCK_ALL_BEGIN() [part 2]
Date: Wed, 13 Oct 2021 22:48:43 +0200 [thread overview]
Message-ID: <20211013204846.90026-18-greenfoo@u92.eu> (raw)
In-Reply-To: <20211013204846.90026-1-greenfoo@u92.eu>
Refactor places using drm_modeset_{lock,unlock}_all() so that they only
appear once per function.
This is needed so that in the next commit I can replace those functions
by the new macros (which use labels that can only appear once per
function).
