Merge tag 'tty-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty/serial updates from Greg KH: "Here is the large set of TTY and Serial driver patches for 5.9-rc1. Lots of bugfixes in here, thanks to syzbot fuzzing for serial and vt and console code. Other highlights include: - much needed vt/vc code cleanup from Jiri Slaby - 8250 driver fixes and additions - various serial driver updates and feature enhancements - locking cleanup for serial/console initializations - other minor cleanups All of these have been in linux-next with no reported issues" * tag 'tty-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (90 commits) MAINTAINERS: enlist Greg formally for console stuff vgacon: Fix for missing check in scrollback handling Revert "serial: 8250: Let serial core initialise spin lock" serial: 8250: Let serial core initialise spin lock tty: keyboard, do not speculate on func_table index serial: stm32: Add RS485 RTS GPIO control serial: 8250_dw: Fix common clocks usage race condition serial: 8250_dw: Pass the same rate to the clk round and set rate methods serial: 8250_dw: Simplify the ref clock rate setting procedure serial: 8250: Add 8250 port clock update method tty: serial: imx: add imx earlycon driver tty: serial: imx: enable imx serial console port as module tty/synclink: remove leftover bits of non-PCI card support tty: Use the preferred form for passing the size of a structure type tty: Fix identation issues in struct serial_struct32 tty: Avoid the use of one-element arrays serial: msm_serial: add sparse context annotation serial: pmac_zilog: add sparse context annotation newport_con: vc_color is now in state serial: imx: use hrtimers for rs485 delays ...
