Merge tag 'fixes-non-critical' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull "ARM: Non-critical bug fixes" from Ardn Bergmann: "Simple bug fixes that were not considered important enough for inclusion into 3.3. One bug fix was originally intended for 3.3 but accidentally got missed, but is not marked stable because it should only get backported once later fixes also make it into v3.4. Signed-off-by: Arnd Bergmann <arnd@arndb.de>" * tag 'fixes-non-critical' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (66 commits) iomux-mx25.h slew rate adjusted for LCD __LD pins ARM: davinci: DA850: move da850_register_pm to .init.text ARM: davinci: cpufreq: fix compiler warning ARM: OMAP2+: Fix build for omap4 only builds with missing include of linux/bug.h ARM: OMAP2+: Fix section warnings for hsmmc_init_one ARM: OMAP2+: Fix build issues with missing include of linux/bug.h ARM: OMAP2+: gpmc-smsc911x: only register regulator for first instance ARM: OMAP3+: PM: VP: fix integer truncation error ARM: OMAP2+: PM: fix wakeupgen warning when hotplug disabled ARM: OMAP2+: PM: fix section mismatch with omap2_init_processor_devices() ARM: OMAP2: Fix section warning for n8x0 when CONFIG_MMC_OMAP is not set ARM: OMAP2+: Fix omap24xx_io_desc warning if SoC subtypes are not selected ARM: OMAP1: Fix section mismatch for omap1_init_early() ARM: OMAP1: Fix typo in lcd_dma.c ARM: OMAP: mailbox: trivial whitespace fix ARM: OMAP: Remove definition cpu_is_omap4430() ARM: OMAP2+: included some headers twice ARM: OMAP: clock.c: included linux/debugfs.h twice ARM: OMAP: don't build hwspinlock in vain ARM: OMAP2+: ads7846_init: put gpio_pendown into pdata if it's provided ...
