[PATCH 00/11] recently added ARM defconfig warnings

These patches address problems that showed up in new warnings
when building all ARM defconfig files in v3.6-rc1 compared
with v3.5.

I can merge them through the arm-soc tree or have subsystem
maintainers pick them up if they prefer.

Arnd Bergmann (11):
  ARM: topology: mark init_cpu_topology as __init
  mfd/asic3: fix asic3_mfd_probe return value
  usb/ohci-omap: remove unused variable
  ARM: ux500: really kill snowball_of_platform_devs
  ARM: exynos: exynos_pm_add_dev_to_genpd may be unused
  gpio: em: do not discard em_gio_irq_domain_cleanup
  net/stmmac: mark probe function as __devinit
  mtd/omap2: fix dmaengine_slave_config error handling
  regulator/twl: remove fixed resource handling
  spi/s3c64xx: improve error handling
  pm/drivers: fix use of SIMPLE_DEV_PM_OPS

Driver probe functions are generally __devinit so they will be
discarded after initialization for non-hotplug kernels.
This was found by a new warning after patch 6a228452d "stmmac: Add
device-tree support" adds a new __devinit function that is called
from stmmac_pltfr_probe.

Without this patch, building socfpga_defconfig results in:

WARNING: drivers/net/ethernet/stmicro/stmmac/stmmac.o(.text+0x5d4c): Section mismatch in reference from the function stmmac_pltfr_probe() to the function .devinit.text:stmmac_probe_config_dt()
The function stmmac_pltfr_probe() references
the function __devinit stmmac_probe_config_dt().
This is often because stmmac_pltfr_probe lacks a __devinit
annotation or the annotation of stmmac_probe_config_dt is wrong.
