====================
pull-request: wireless-drivers-next 2015-01-22

now a bigger pull request for net-next. Rafal found a UTF-8 bug in
patchwork[1] and because of that two commits (d0c102f70aec and
d0f66df5392a) have his name corrupted:

    Acked-by: Rafa? Mi?ecki <zajec5@gmail.com>

Somehow I failed to spot that when I commited the patches. As rebasing
public git trees is bad, I thought we can live with these and decided
not to rebase. But I'll pay close attention to this in the future to
make sure that it won't happen again. Also we requested an update to
patchwork.kernel.org, the latest patchwork doesn't seem to have this
bug.

Also please note this pull request also adds one DT binding doc, but
this was reviewed in the device tree list:

 .../bindings/net/wireless/qcom,ath10k.txt          |   30 +

Please let me know if you have any issues.
