Subject: [PATCH 1/2] ath10k: wmi: match wait_for_completion_timeout return type

return type of wait_for_completion_timeout is unsigned long not int. This
patch adjusts the type and name of the return variable and adjusts the 
success/fail values to match those used at the call site in ath10k_core_start

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

Adjustment of return values was proposed by Michal Kazior
<michal.kazior@...to.com> - thanks!

Patch was only compile tested with x86_64_defconfig + CONFIG_ATH_CARDS=m,
CONFIG_ATH10K=m

Patch is against 4.0-rc3 (localversion-next is -next-20150313)
