Subject: [PATCH 2/2] drm/debugfs: add descriptions to struct parameters
Date:   Thu,  5 Jan 2023 16:30:39 -0300

The structs drm_debugfs_info and drm_debugfs_entry don't have
descriptions for their parameters, which is causing the following warnings:

include/drm/drm_debugfs.h:93: warning: Function parameter or member
'name' not described in 'drm_debugfs_info'
include/drm/drm_debugfs.h:93: warning: Function parameter or member
'show' not described in 'drm_debugfs_info'
include/drm/drm_debugfs.h:93: warning: Function parameter or member
'driver_features' not described in 'drm_debugfs_info'
include/drm/drm_debugfs.h:93: warning: Function parameter or member
'data' not described in 'drm_debugfs_info'
include/drm/drm_debugfs.h:105: warning: Function parameter or member
'dev' not described in 'drm_debugfs_entry'
include/drm/drm_debugfs.h:105: warning: Function parameter or member
'file' not described in 'drm_debugfs_entry'
include/drm/drm_debugfs.h:105: warning: Function parameter or member
'list' not described in 'drm_debugfs_entry'

Therefore, fix the warnings by adding descriptions to all struct
parameters.
