Merge tag 'tty-4.15-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty/serial driver fixes from Greg KH:
"Here are some small serdev and serial fixes for 4.15-rc3. They resolve
some reported problems:
- a number of serdev fixes to resolve crashes
- MIPS build fixes for their serial port
- a new 8250 device id
All of these have been in linux-next for a while with no reported
issues"
* tag 'tty-4.15-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty:
MIPS: Add custom serial.h with BASE_BAUD override for generic kernel
serdev: ttyport: fix tty locking in close
serdev: ttyport: fix NULL-deref on hangup
serdev: fix receive_buf return value when no callback
serdev: ttyport: add missing receive_buf sanity checks
serial: 8250_early: Only set divisor if valid clk & baud
serial: 8250_pci: Add Amazon PCI serial device ID
