Merge tag 'tty-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull TTY changes from Greg Kroah-Hartman: "As we skipped the merge window for 3.6-rc1 for the tty tree, everything is now settled down and working properly, so we are ready for 3.7-rc1. Here's the patchset, it's big, but the large changes are removing a firmware file and adding a staging tty driver (it depended on the tty core changes, so it's going through this tree instead of the staging tree.) All of these patches have been in the linux-next tree for a while. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>" Fix up more-or-less trivial conflicts in - drivers/char/pcmcia/synclink_cs.c: tty NULL dereference fix vs tty_port_cts_enabled() helper function - drivers/staging/{Kconfig,Makefile}: add-add conflict (dgrp driver added close to other staging drivers) - drivers/staging/ipack/devices/ipoctal.c: "split ipoctal_channel from iopctal" vs "TTY: use tty_port_register_device" * tag 'tty-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (235 commits) tty/serial: Add kgdb_nmi driver tty/serial/amba-pl011: Quiesce interrupts in poll_get_char tty/serial/amba-pl011: Implement poll_init callback tty/serial/core: Introduce poll_init callback kdb: Turn KGDB_KDB=n stubs into static inlines kdb: Implement disable_nmi command kernel/debug: Mask KGDB NMI upon entry serial: pl011: handle corruption at high clock speeds serial: sccnxp: Make 'default' choice in switch last serial: sccnxp: Remove mask termios caps for SW flow control serial: sccnxp: Report actual baudrate back to core serial: samsung: Add poll_get_char & poll_put_char Powerpc 8xx CPM_UART setting MAXIDL register proportionaly to baud rate Powerpc 8xx CPM_UART maxidl should not depend on fifo size Powerpc 8xx CPM_UART too many interrupts Powerpc 8xx CPM_UART desynchronisation serial: set correct baud_base for EXSYS EX-41092 Dual 16950 serial: omap: fix the reciever line error case 8250: blacklist Winbond CIR port 8250_pnp: do pnp probe before legacy probe ...
