Subject: [PATCH] drm/v3d: centralize error handling when init scheduler fails
Date:   Mon, 28 Feb 2022 17:16:47 -0100
Message-Id: <20220228181647.3794298-1-mwen@igalia.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Remove redundant error message (since now it is very similar to what
we do in drm_sched_init) and centralize all error handling in a
unique place, as we follow the same steps in any case of failure.
