i don't see how fixing the C file solves this issue. the header file <linux/tty_driver.h> clearly refers to "struct ktermios", for which it won't have a definition unless it includes <asm/termbits.h>.
you can hack a solution by explicitly including the latter first, of course, but i don't see how that constitutes a proper fix. or am i misreading something here?

p.s. this isn't just theoretical -- this bit me this morning as i was writing a simple module to flash the keyboard LEDs, just for the entertainment value.
