From: Shixiong Ou <oushixiong@xxxxxxxxxx>
[WHY]
1. The driver forgot to call device_remove_file()
in sh_mobile_lcdc_overlay_fb_unregister(), and there was
no error handling when calling device_create_file() failed.
2. This should probably use device_add_group() instead of
individual files to simplify both creation and removal. [Arnd]
3. The driver core can register and cleanup sysfs groups already.
as commit 95cdd538e0e5 ("fbdev: efifb: Register sysfs groups
through driver core").
[HOW]
Register sysfs groups through driver core.
