Merge tag 'tty-3.3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull TTY/serial patches from Greg KH: "tty and serial merge for 3.4-rc1 Here's the big serial and tty merge for the 3.4-rc1 tree. There's loads of fixes and reworks in here from Jiri for the tty layer, and a number of patches from Alan to help try to wrestle the vt layer into a sane model. Other than that, lots of driver updates and fixes, and other minor stuff, all detailed in the shortlog." * tag 'tty-3.3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (132 commits) serial: pxa: add clk_prepare/clk_unprepare calls TTY: Wrong unicode value copied in con_set_unimap() serial: PL011: clear pending interrupts serial: bfin-uart: Don't access tty circular buffer in TX DMA interrupt after it is reset. vt: NULL dereference in vt_do_kdsk_ioctl() tty: serial: vt8500: fix annotations for probe/remove serial: remove back and forth conversions in serial_out_sync serial: use serial_port_in/out vs serial_in/out in 8250 serial: introduce generic port in/out helpers serial: reduce number of indirections in 8250 code serial: delete useless void casts in 8250.c serial: make 8250's serial_in shareable to other drivers. serial: delete last unused traces of pausing I/O in 8250 pch_uart: Add module parameter descriptions pch_uart: Use existing default_baud in setup_console pch_uart: Add user_uartclk parameter pch_uart: Add Fish River Island II uart clock quirks pch_uart: Use uartclk instead of base_baud mpc5200b/uart: select more tolerant uart prescaler on low baudrates tty: moxa: fix bit test in moxa_start() ...
