Subject: [PATCH v2 08/17] drm/msm: remove checks for return value of drm_debugfs_create_files()
Date: Tue, 10 Mar 2020 16:31:12 +0300 [thread overview]
Message-ID: <20200310133121.27913-9-wambui.karugax@gmail.com> (raw)
In-Reply-To: <20200310133121.27913-1-wambui.karugax@gmail.com>
Since commit 987d65d01356 (drm: debugfs: make
drm_debugfs_create_files() never fail), drm_debugfs_create_files never
fails and only returns 0. Therefore, the unnecessary checks for its
return value and error handling in various debugfs_init() functions in
drm/msm and have the functions return 0 directly.
v2: have debug functions return 0 instead of void to avoid build
breakage and ensure standalone compilation.
