Merge tag 'tty-5.6-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 updates for 5.6-rc1 Included in here are: - dummy_con cleanups (touches lots of arch code) - sysrq logic cleanups (touches lots of serial drivers) - samsung driver fixes (wasn't really being built) - conmakeshash move to tty subdir out of scripts - lots of small tty/serial driver updates All of these have been in linux-next for a while with no reported issues" * tag 'tty-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (140 commits) tty: n_hdlc: Use flexible-array member and struct_size() helper tty: baudrate: SPARC supports few more baud rates tty: baudrate: Synchronise baud_table[] and baud_bits[] tty: serial: meson_uart: Add support for kernel debugger serial: imx: fix a race condition in receive path serial: 8250_bcm2835aux: Document struct bcm2835aux_data serial: 8250_bcm2835aux: Use generic remapping code serial: 8250_bcm2835aux: Allocate uart_8250_port on stack serial: 8250_bcm2835aux: Suppress register_port error on -EPROBE_DEFER serial: 8250_bcm2835aux: Suppress clk_get error on -EPROBE_DEFER serial: 8250_bcm2835aux: Fix line mismatch on driver unbind serial_core: Remove unused member in uart_port vt: Correct comment documenting do_take_over_console() vt: Delete comment referencing non-existent unbind_con_driver() arch/xtensa/setup: Drop dummy_con initialization arch/x86/setup: Drop dummy_con initialization arch/unicore32/setup: Drop dummy_con initialization arch/sparc/setup: Drop dummy_con initialization arch/sh/setup: Drop dummy_con initialization arch/s390/setup: Drop dummy_con initialization ...
