[PATCH] ath10k: match wait_for_completion_timeout return type

[Will]

Hello,

Sorry to bother you all, but I'm one of a few people affected by the
problem described in this thread (which is also on launchpad;
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1383184).

Is there anything I can do to help things along? Whether it be testing
or (...if someone pointed me in the right direction...) coding, I'd
like to help out, and so maybe get my wi-fi card working :D

Thanks!

Will
