Subject: [PATCH v2 11/17] drm/nouveau: make nouveau_drm_debugfs_init() return 0
Date: Tue, 10 Mar 2020 16:31:15 +0300 [thread overview]
Message-ID: <20200310133121.27913-12-wambui.karugax@gmail.com> (raw)
In-Reply-To: <20200310133121.27913-1-wambui.karugax@gmail.com>
Since 987d65d01356 (drm: debugfs: make
drm_debugfs_create_files() never fail), there is no need to ever check
for the the return value of debugfs_create_file() and
drm_debugfs_create_files(). Therefore, remove unnecessary checks and
error handling in nouveau_drm_debugfs_init() and have the function
return 0 directly.
v2: have nouveau_drm_debugfs_init() return 0 instead of void so as not
to introduce any build warnings to enable individual patch compilation.
