Frankly, I wish you hadn't. The patch changed the perfectly fine:
int vga_switcheroo_register_handler(const struct vga_switcheroo_handler *handler,
enum vga_switcheroo_handler_flags_t handler_flags)
into horrendous:
int vga_switcheroo_register_handler(
const struct vga_switcheroo_handler *handler,
enum vga_switcheroo_handler_flags_t handler_flags)
Just to appease the 80 column rule. Ditto for
vga_switcheroo_register_audio_client. This is why we don't generally
want pure checkpatch fixes on existing files. They don't make things
better.
BR,
Jani.
