Merge branch 'omap-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6
* 'omap-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6:
OMAP2: PRCM: fix some SHIFT macros that were actually bitmasks
OMAP2+: PM/serial: fix console semaphore acquire during suspend
OMAP1: SRAM: fix size for OMAP1611 SoCs
arm: omap2: io: fix clk_get() error check
arm: plat-omap: counter_32k: use IS_ERR() instead of NULL check
omap: nand: remove hardware ECC as default
omap: zoom: wl1271 slot is MMC_CAP_POWER_OFF_CARD
omap: PM debug: fix wake-on-timer debugfs dependency
