Subject: [PATCH] omap-serial: Allow IXON and IXOFF to be disabled.
Date: Fri, 15 Jul 2011 13:53:08 -0700 [thread overview]
Message-ID: <1310763188-21248-1-git-send-email-npelly@google.com> (raw)
Fixes logic bug that software flow control cannot be disabled, because
serial_omap_configure_xonxoff() is not called if both IXON and IXOFF bits
are cleared.
