  tty: tty_ldisc: Fix some kernel-doc related misdemeanours
  tty: vt: consolemap: Demote weakly documented function header

  tty: serial: jsm: jsm_cls: Remove unused variable 'discard'
  tty: tty_io: Fix some kernel-doc issues

    pointers
  tty: serial: 8250: serial_cs: Remove unused/unchecked variable 'err'
  tty: tty_audit: Demote non-conformant kernel-doc headers
  tty: pty: Provide descriptions for the 'file' parameters
  tty: serial: amba-pl011: Mark 'sbsa_uart_acpi_match' as __maybe_unused
  tty: n_gsm: Demote obvious abuse of kernel-doc and supply other
    missing docss
  tty: serial: lpc32xx_hs: Remove unused variable 'tmp'
  tty: serial: msm_serial: Remove set but unused variable 'status'
  tty: serial: ifx6x60: Fix function documentation headers
  tty: serial: xilinx_uartps: Supply description for missing member
    'cts_override'
  tty: synclink_gt: Demote one kernel-doc header and repair another
  tty: serial: serial-tegra: Struct headers should start with 'struct
    <name>'
  tty: serial: sifive: Struct headers should start with 'struct <name>'
  tty: synclinkmp: Add missing description for function param 'txqueue'
  tty: synclinkmp: Mark never checked 'readval' as __always_unused
  tty: serial: stm32-usart: Remove set but unused 'cookie' variables
  tty: tty_ldisc: Supply missing description for 'tty_ldisc_get's 'tty'
    param
  tty: serial: serial-tegra: Provide some missing struct member
    descriptions
  powerpc: asm: hvconsole: Move 'hvc_vio_init_early's prototype to
    shared location
  tty: hvc: hvc_vio: Staticify function invoked only by reference
  tty: hvc: hvc_opal: Staticify function invoked by reference
  tty: serial: pmac_zilog: Make disposable variable __always_unused
  tty: synclink: Mark disposable variables as __always_unused
  tty: synclink: Provide missing description for 'hdlcdev_tx_timeout's
