2011-04-22tty: make receive_buf() return the amout of bytes receivedFelipe Balbi1-4/+6
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.

These were missed the last time I cleaned this up globally, because of code moving around or new code getting merged. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2010-11-05TTY: create drivers/tty and move the tty core files thereGreg Kroah-Hartman1-0/+1264
The tty code should be in its own subdirectory and not in the char driver with all of the cruft that is currently there.
