[PATCH v2 00/20] mwifiex: "reset" bugfixes and other refactorings

[Brian Norris]

Hello,

I've previously sent a stack of similar patches (with no cover letter),
starting at this patch:

[PATCH 01/14] mwifiex: pcie: properly synchronize, disable interrupts in driver callbacks
http://www.mail-archive.com/linux-kernel@xxxxxxxxxxxxxxx/msg1405062.html
https://patchwork.kernel.org/patch/9747263/

They fixed several bugs related to the "reset" codepath in this driver,
in which the driver tries to recover from a dead firmware, as well as making
various code improvements (e.g., refactorings, removing redunancy, improving
safety).

There were some valid criticisms of the first patch in that series (and some
real issues I hit with it later on in testing), and in the end, I believe
the concern there was not actually appearing in practice, so in order to
make some forward progress, I've dropped that patch (and related changes)
from this series. I've kept most of the rest and added a few bugfixes along
the way.

Thanks to Johannes for some brainstorming/ideas that yielded the patch
"mwifiex: unregister wiphy before freeing resources".

Regards,
Brian
