From 23198fda7182969b619613a555f8645fdc3dc334 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Mon, 20 Jul 2009 16:05:27 +0100 Subject: 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.
