Subject: [PATCH 13/21] drm/omapdrm: remove checks for return value of drm_debugfs functions.
Date: Thu, 27 Feb 2020 15:02:24 +0300	[thread overview]
Message-ID: <20200227120232.19413-14-wambui.karugax@gmail.com> (raw)
In-Reply-To: <20200227120232.19413-1-wambui.karugax@gmail.com>

Since 987d65d01356 (drm: debugfs: make
drm_debugfs_create_files() never fail), there is no need to ever check
the return value for drm_debugfs_create_files(). Therefore remove the
checks for the return value and subsequent error handling in
omap_debugfs_init().

These changes also enables the changing of omap_debugfs_init() to return
void.
