Merge tag 'tty-6.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty / serial fixes from Greg KH: "Here are some small tty and serial driver fixes for 6.11-rc4 to resolve some reported problems. Included in here are: - conmakehash.c userspace build issues - fsl_lpuart driver fix - 8250_omap revert for reported regression - atmel_serial rts flag fix All of these have been in linux-next this week with no reported issues" * tag 'tty-6.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: Revert "serial: 8250_omap: Set the console genpd always on if no console suspend" tty: atmel_serial: use the correct RTS flag. tty: vt: conmakehash: remove non-portable code printing comment header tty: serial: fsl_lpuart: mark last busy before uart_add_one_port
