Merge tag 'tty-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull TTY changes from Greg Kroah-Hartman:
"As we skipped the merge window for 3.6-rc1 for the tty tree,
everything is now settled down and working properly, so we are ready
for 3.7-rc1. Here's the patchset, it's big, but the large changes are
removing a firmware file and adding a staging tty driver (it depended
on the tty core changes, so it's going through this tree instead of
the staging tree.)
All of these patches have been in the linux-next tree for a while.
Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>"
Fix up more-or-less trivial conflicts in
- drivers/char/pcmcia/synclink_cs.c:
tty NULL dereference fix vs tty_port_cts_enabled() helper function
- drivers/staging/{Kconfig,Makefile}:
add-add conflict (dgrp driver added close to other staging drivers)
- drivers/staging/ipack/devices/ipoctal.c:
"split ipoctal_channel from iopctal" vs "TTY: use tty_port_register_device"
