drivers/char/synclink.c: unbreak mgsl_put_char()
Repair the effects of commit 55da77899c1472d83452c914fa179d00ea96df65 Author: Alan Cox <alan@lxorguk.ukuu.org.uk> Date: Wed Apr 30 00:54:07 2008 -0700 synclink series: switch to int put_char method Signed-off-by: Alan Cox <alan@redhat.com> Cc: Paul Fulghum <paulkf@microgate.com> Cc: Jiri Slaby <jirislaby@gmail.com> drivers/char/synclink_gt.c: In function 'put_char': drivers/char/synclink_gt.c:919: warning: 'ret' may be used uninitialized in this function and do some whitespace repair and unneeded-cast-removal in there as well.
