tty: fix chars_in_buffers
This function does not have an error return and returning an error is instead interpreted as having a lot of pending bytes. Reported by Jeff Harris who provided a list of some of the remaining offenders. Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
