CHECK: No space is necessary after a cast

Please run checkpatch --strict on your patches. Never mind, I'll apply the
patch anyway - I see the other entries are the same.

That makes me have a closer look at the code. What is the purpose of the
odd typecast anyway ? Why not just
	.driver_data = (void *)aya_neo_2,
and
	board = (enum oxp_board)dmi_entry->driver_data;
?
