These patches all fix bugs that were newly introduced in v3.6-rc1
and found because they cause a gcc warning with one of the ARM
defconfigs. Most of them are harmless, but since we're trying
to get rid of all warnings eventually, we can start with the ones
that were not there before.
* testing/new-warnings:
omap-rng: fix use of SIMPLE_DEV_PM_OPS
spi/s3c64xx: improve error handling
mtd/omap2: fix dmaengine_slave_config error handling
gpio: em: do not discard em_gio_irq_domain_cleanup
ARM: exynos: exynos_pm_add_dev_to_genpd may be unused
usb/ohci-omap: remove unused variable
mfd/asic3: fix asic3_mfd_probe return value
