Subject: [PATCH v19 01/30] drm/gem: Change locked/unlocked postfix of drm_gem_v/unmap() function names
Date: Fri,  5 Jan 2024 21:45:55 +0300
Message-ID: <20240105184624.508603-2-dmitry.osipenko@collabora.com>
In-Reply-To: <20240105184624.508603-1-dmitry.osipenko@collabora.com>

Make drm/gem API function names consistent by having locked function
use the _locked postfix in the name, while the unlocked variants don't
use the _unlocked postfix. Rename drm_gem_v/unmap() function names to
make them consistent with the rest of the API functions.
