Subject: linux-next: manual merge of the tty tree with the bluetooth tree

Hi Greg,

Today's linux-next merge of the tty tree got a conflict in:


between commits:

  b3f80c8f75ef ("serdev: add serdev_device_wait_until_sent")
  5659dab26f09 ("serdev: implement get/set tiocm")

from the bluetooth tree and commit:

  6fe729c4bdae ("serdev: Add serdev_device_write subroutine")

from the tty tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
