Subject: [PATCH v2 09/17] drm/sti: remove use of drm_debugfs functions as return values
Date: Tue, 10 Mar 2020 16:31:13 +0300	[thread overview]
Message-ID: <20200310133121.27913-10-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. This change therefore removes it uses as
a return value in various functions across drm/sti.

With these changes, the affected functions have been changed to use a void
return value.

v2: convert sti_mixer_debugfs_init() and sti_compositor_debugfs_init()
to return void too. Also have sti_drm_dbg_init() to return 0 to avoid
build issues.
