Subject: [PATCH 08/21] drm/etnaviv: remove check for return value of drm_debugfs function
Date: Thu, 27 Feb 2020 15:02:19 +0300	[thread overview]
Message-ID: <20200227120232.19413-9-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_file only
returns 0, and there is no need to check the return value.
This change therefore removes the check and error handling in
etnaviv_debugfs_init() and also makes the function return void.
