Merge tag 'tty-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty/serial updates from Greg KH: "Here is the big tty/serial driver pull request for 4.15-rc1. Lots of serial driver updates in here, some small vt cleanups, and a raft of SPDX and license boilerplate cleanups, messing up the diffstat a bit. Nothing major, with no realy functional changes except better hardware support for some platforms. All of these have been in linux-next for a while with no reported issues" * tag 'tty-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (110 commits) tty: ehv_bytechan: fix spelling mistake tty: serial: meson: allow baud-rates lower than 9600 serial: 8250_fintek: Fix crash with baud rate B0 serial: 8250_fintek: Disable delays for ports != 0 serial: 8250_fintek: Return -EINVAL on invalid configuration tty: Remove redundant license text tty: serdev: Remove redundant license text tty: hvc: Remove redundant license text tty: serial: Remove redundant license text tty: add SPDX identifiers to all remaining files in drivers/tty/ tty: serial: jsm: remove redundant pointer ts tty: serial: jsm: add space before the open parenthesis '(' tty: serial: jsm: fix coding style tty: serial: jsm: delete space between function name and '(' tty: serial: jsm: add blank line after declarations tty: serial: jsm: change the type of local variable tty: serial: imx: remove dead code imx_dma_rxint tty: serial: imx: disable ageing timer interrupt if dma in use serial: 8250: fix potential deadlock in rs485-mode serial: m32r_sio: Drop redundant .data assignment ...
