return type of wait_for_completion_timeout is unsigned long not int, this
patch adds an appropriate variable and fixes up the assignment.
As the string in dev_err already explicitly states "timeout" there
is little point in printing the 0 here which also just says "timeout".

This patch was only compile tested with tegra_defconfig
(implies CONFIG_SPI_TEGRA114=y)

Patch is against 3.19.0-rc6 -next-20150130

Looks good to me. Thanks for fixing this.
I think it is good if we fix the typo here also.
