TTY/Serial fixes for 4.11-rc2

Here are 2 bugfixes for tty stuff for 4.11-rc2.  One of them resolves
the pretty bad bug in the n_hdlc code that Alexander Popov found and
fixed and has been reported everywhere.  The other just fixes a samsung
serial driver issue when DMA fails on some systems.

Both have been in linux-next with no reported issues.
