Subject: [PATCH v2 07/14] drm/ast: Don't enable HW cursors twice during atomic update
Date: Thu,  2 Jul 2020 13:50:22 +0200	[thread overview]
Message-ID: <20200702115029.5281-8-tzimmermann@suse.de> (raw)
In-Reply-To: <20200702115029.5281-1-tzimmermann@suse.de>

The ast_cursor_show() helper enables the cursor to be displayed. No need
to repeat that operation in the plane's atomic-update function.
