[PATCH] mtd: nand: gpmi: fixup return type of wait_for_completion_timeout

[Nicholas Mc Guire]

return type of wait_for_completion_timeout is unsigned long not int. The
return variable is renamed to reflect its use and the type adjusted to
unsigned long.

Patch was only compile tested with imx_v6_v7_defconfig
(implies CONFIG_MTD_NAND_GPMI_NAND=y)

Patch is against 3.19.0-rc7 (localversion-next is -next-20150204)
