Subject: pull request: wireless 2013-02-25
Dave,
This is a batch of fixes intended for the 3.9 stream...
Avinash Patil gives us a mwifiex fix to prevent a system freeze when
that driver is unloaded.
Daniel Drake brings a patch to avoid dropping the carrier flag across a
suspend. This prevents improper packet drops.
Wei Yongjun delivers a brcmfmac for a lock leak on an error path.
Please let me know if there are problems!
Thanks,
John
