[1/2] spi: tegra20-sflash: cleanup wait_for_completion return handling

Commit Message

Nicholas Mc Guire Feb. 1, 2015, 1 p.m. UTC

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 states "timeout" there
is little point in printing the 0 here.

This patch was only compile tested with tegra_defconfig
(implies CONFIG_SPI_TEGRA20_SFLASH=y)

Patch is against 3.19.0-rc6 -next-20150130
