Pull TTY/Serial merge from Greg Kroah-Hartman: "Here's the big tty/serial tree set of changes for 3.8-rc1. Contained in here is a bunch more reworks of the tty port layer from Jiri and bugfixes from Alan, along with a number of other tty and serial driver updates by the various driver authors. Also, Jiri has been coerced^Wconvinced to be the co-maintainer of the TTY layer, which is much appreciated by me. All of these have been in the linux-next tree for a while. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>" Fixed up some trivial conflicts in the staging tree, due to the fwserial driver having come in both ways (but fixed up a bit in the serial tree), and the ioctl handling in the dgrp driver having been done slightly differently (staging tree got that one right, and removed both TIOCGSOFTCAR and TIOCSSOFTCAR). * tag 'tty-3.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (146 commits) staging: sb105x: fix potential NULL pointer dereference in mp_chars_in_buffer() staging/fwserial: Remove superfluous free staging/fwserial: Use WARN_ONCE when port table is corrupted staging/fwserial: Destruct embedded tty_port on teardown staging/fwserial: Fix build breakage when !CONFIG_BUG staging: fwserial: Add TTY-over-Firewire serial driver drivers/tty/serial/serial_core.c: clean up HIGH_BITS_OFFSET usage staging: dgrp: dgrp_tty.c: Audit the return values of get/put_user() staging: dgrp: dgrp_tty.c: Remove the TIOCSSOFTCAR ioctl handler from dgrp driver serial: ifx6x60: Add modem power off function in the platform reboot process serial: mxs-auart: unmap the scatter list before we copy the data serial: mxs-auart: disable the Receive Timeout Interrupt when DMA is enabled serial: max310x: Setup missing "can_sleep" field for GPIO tty/serial: fix ifx6x60.c declaration warning serial: samsung: add devicetree properties for non-Exynos SoCs serial: samsung: fix potential soft lockup during uart write tty: vt: Remove redundant null check before kfree. tty/8250 Add check for pci_ioremap_bar failure tty/8250 Add support for Commtech's Fastcom Async-335 and Fastcom Async-PCIe cards tty/8250 Add XR17D15x devices to the exar_handle_irq override ...
