Subject: [PATCH v2 15/17] drm: make various debugfs_init() functions return 0
Date:   Tue, 10 Mar 2020 16:31:19 +0300

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.
