Subject: [PATCH] hv: channel: match var type to return type of wait_for_completion

From: Nicholas Mc Guire <der.herr@...r.at>

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

Signed-off-by: Nicholas Mc Guire <der.herr@...r.at>

The return type of wait_for_completion_timeout is unsigned long not
int. This patch resolves the type missmatch by changing the type
to unsigned long.

This patch was only compile tested with x86_64_defconfig +
CONFIG_X86_VSMP=y, CONFIG_HYPERV=m

Patch is against 3.19.0-rc6 -next-20150130
