ENGR00118016-3 wm8580: update to 2.6.31
wm8580 is using regulators that can't change state. The
regulator driver doesn't handle this case well so it crashes
during regulator_bulk_enable. Eventually this will be fixed in the
regulator driver. For now, remove regulators from list in
wm8580 driver.
Fix spi_rw err. hw_write needs to return transferred data length.
