[PATCH 6/8] backlight: backlight: Supply description for function args in existing Kerneldocs

Wed Jun 24 10:57:19 EDT 2020


Kerneldoc syntax is used, but not complete.  Descriptions required.

Prevents warnings like:

 drivers/video/backlight/backlight.c:329: warning: Function parameter or member 'reason' not described in 'backlight_force_update'
 drivers/video/backlight/backlight.c:354: warning: Function parameter or member 'props' not described in 'backlight_device_register'
