Subject: [PATCH] crypto: mxs-dcp: fix type of ret for wait_for_completion_timeout

return type of wait_for_completion_timeout is unsigned long not int, this
patch changes the type of ret from int to unsigned long.

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

As ret is only used here for wait_for_completion_timeout it can simply
be changed to the appropriate type.

Patch was only compile tested with mxs_defconfig 
(implies CONFIG_CRYPTO_DEV_MXS_DCP=y)

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