Subject: [PATCH v2 15/17] drm: make various debugfs_init() functions return 0
Date: Tue, 10 Mar 2020 16:31:19 +0300	[thread overview]
Message-ID: <20200310133121.27913-16-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 should return void. Therefore, remove its use as the
return value of various debugfs_init() functions in drm, and have these
functions return 0 directly.

v2: convert debugfs_init() functions to return 0 instead of void to
avoid build breakage.
