[PATCH] ASoC: arizona: match wait_for_completion_timeout return type

[Nicholas Mc Guire <hofrat@osadl.org>]

return type of wait_for_completion_timeout is unsigned long not int. An
appropriately named unsigned long is added and the assignment fixed up.

Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org>

Note that the error message
 "Timed out waiting for lock"
might not be that clear in a kernel log message as it 
could probably be read as relating to a kernel lock 
 "Timed out waiting for FLL lock"
might be clearer.

This was only compile tested for exynos_defconfig + CONFIG_COMPILE_TEST=y
SND_SOC_ALL_CODECS=m, EXTCON_ARIZONA=m, CONFIG_MFD_ARIZONA_SPI=m, 
CONFIG_MFD_WM5102=y, (implies SND_SOC_ARIZONA=m)

Patch is against 4.0-rc2 linux-next (localversion-next is -next-20150306)
