[PATCH 1/2] ASoC: wm8996: match wait_for_completion_timeout return type

[Nicholas Mc Guire]

return type of wait_for_completion_timeout is unsigned long not int. An
appropriately named unsigned long is added and the assignment fixed up
in case of completion occurring the remaining time is >=1 so ret is set to
1 if no timeout occurred.

This was only compile tested for exynos_defconfig + CONFIG_COMPILE_TEST=y, 
SND_SOC_ALL_CODECS=m (implies CONFIG_SND_SOC_WM8996=m)

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