Merge tag 'tty-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty/serial driver updates from Greg KH: "Here are the big set of tty and serial driver changes for 5.18-rc1. Nothing major, some more good cleanups from Jiri and 2 new serial drivers. Highlights include: - termbits cleanups - export symbol cleanups and other core cleanups from Jiri Slaby - new sunplus and mvebu uart drivers (amazing that people are still creating new uarts...) - samsung serial driver cleanups - ldisc 29 is now "reserved" for experimental/development line disciplines - lots of other tiny fixes and cleanups to serial drivers and bindings All of these have been in linux-next for a while with no reported issues" * tag 'tty-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (104 commits) vt_ioctl: fix potential spectre v1 in VT_DISALLOCATE serial: 8250: fix XOFF/XON sending when DMA is used tty: serial: samsung: Add ARTPEC-8 support dt-bindings: serial: samsung: Add ARTPEC-8 UART serial: sc16is7xx: Clear RS485 bits in the shutdown tty: serial: samsung: simplify getting OF match data tty: serial: samsung: constify variables and pointers tty: serial: samsung: constify s3c24xx_serial_drv_data members tty: serial: samsung: constify UART name tty: serial: samsung: constify s3c24xx_serial_drv_data tty: serial: samsung: reduce number of casts tty: serial: samsung: embed s3c2410_uartcfg in parent structure tty: serial: samsung: embed s3c24xx_uart_info in parent structure serial: 8250_tegra: mark acpi_device_id as unused with !ACPI tty: serial: bcm63xx: use more precise Kconfig symbol serial: SERIAL_SUNPLUS should depend on ARCH_SUNPLUS tty: serial: jsm: fix two assignments in if conditions tty: serial: jsm: remove redundant assignments to variable linestatus serial: 8250_mtk: make two read-only arrays static const serial: samsung_tty: do not unlock port->lock for uart_write_wakeup() ...
