Subject: [PATCH] wil6210: match wait_for_completion_timeout return type

Return type of wait_for_completion_timeout is unsigned long not int.
As remain is exclusively used for wait_for_completion_timeout here its
type is simply changed to unsigned long.


API conformance testing for completions with coccinelle spatches are being
used to locate API usage inconsistencies:
./drivers/net/wireless/ath/wil6210/wmi.c:827 
	int return assigned to unsigned long

Patch was compile tested with x86_64_defconfig + CONFIG_ATH_CARDS=m,
CONFIG_WIL6210=m

Patch is against 4.1-rc3 (localversion-next is -next-20150514)
