Subject: [PATCH 15/21] drm/sti: remove use drm_debugfs functions as return value
Date: Thu, 27 Feb 2020 15:02:26 +0300	[thread overview]
Message-ID: <20200227120232.19413-16-wambui.karugax@gmail.com> (raw)
In-Reply-To: <20200227120232.19413-1-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.
