Did you try to compile, say, arm:allmodconfig with this patch applied ?
Because for me that results in:

In file included from <command-line>:
drivers/firmware/stratix10-rsu.c: In function 'rsu_status_callback':
include/linux/compiler_types.h:320:38: error:
	call to '__compiletime_assert_177' declared with attribute error:
	FIELD_GET: type of reg too small for mask

and lots of similar errors.
