Merge tag 'tty-5.5-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 and serial driver patches for 5.5-rc1. It's a bit later in the merge window than normal as I wanted to make sure some last-minute patches applied to it were all sane. They seem to be :) There's a lot of little stuff in here, for the tty core, and for lots of serial drivers: - reverts of uartlite serial driver patches that were wrong - msm-serial driver fixes - serial core updates and fixes - tty core fixes - serial driver dma mapping api changes - lots of other tiny fixes and updates for serial drivers All of these have been in linux-next for a while with no reported issues" * tag 'tty-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (58 commits) Revert "serial/8250: Add support for NI-Serial PXI/PXIe+485 devices" vcs: prevent write access to vcsu devices tty: vt: keyboard: reject invalid keycodes tty: don't crash in tty_init_dev when missing tty_port serial: stm32: fix clearing interrupt error flags tty: Fix Kconfig indentation, continued serial: serial_core: Perform NULL checks for break_ctl ops tty: remove unused argument from tty_open_by_driver() tty: Fix Kconfig indentation {tty: serial, nand: onenand}: samsung: rename to fix build warning serial: ifx6x60: add missed pm_runtime_disable serial: pl011: Fix DMA ->flush_buffer() Revert "serial-uartlite: Move the uart register" Revert "serial-uartlite: Add get serial id if not provided" Revert "serial-uartlite: Do not use static struct uart_driver out of probe()" Revert "serial-uartlite: Add runtime support" Revert "serial-uartlite: Change logic how console_port is setup" Revert "serial-uartlite: Use allocated structure instead of static ones" tty: serial: msm_serial: Use dma_request_chan() directly for channel request tty: serial: tegra: Use dma_request_chan() directly for channel request ...
