git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core update from Greg KH: "Here's the set of driver core patches for 3.19-rc1. They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes. There are some ath9k patches coming in through this tree that have been acked by the wireless maintainers as they relied on the debugfs changes.

2013-04-27ARM: u300: fix ages old copy/paste bugLinus Walleij1-1/+1
The UART1 is on the fast AHB bridge, not on the slow bus. Cc: stable@vger.kernel.org Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Olof Johansson <olof@lixom.net>

git://git.linaro.org/people/shawnguo/linux-2.6 into next/cleanup From Shawn Guo: The series cleans up ARCH_HAS_DECOMP_WDOG and arch_decomp_wdog which are unused on ARM architecure. Samsung has some code setting up wdog in arch_decomp_wdog(). But since CONFIG_S3C_BOOT_WATCHDOG is defined nowhere, it will not run. Otherwise, system can not boot at all when wdog is set up but no one pats it. * tag 'cleanup-decompwdog-3.9' of git://git.linaro.org/people/shawnguo/linux-2.6: ARM: samsung: remove unused arch_decomp_wdog() code ARM: remove unused arch_decomp_wdog() ARM: decompress: remove unused ARCH_HAS_DECOMP_WDOG Signed-off-by: Olof Johansson <olof@lixom.net>
