b1c43f82c5 tty: make receive_buf() return the amout of bytes received 
it makes it simpler to keep track of the amount of
bytes received and simplifies how flush_to_ldisc counts
the remaining bytes. It also fixes a bug of lost bytes
on n_tty when flushing too many bytes via the USB
serial gadget driver.

5edc341313 drivers: remove extraneous includes of smp_lock.h 
These were missed the last time I cleaned this up
globally, because of code moving around or new code
getting merged.

96fd7ce58f TTY: create drivers/tty and move the tty core files there 
The tty code should be in its own subdirectory and not in the char
driver with all of the cruft that is currently there.
