Hey,
I'm working on making sta_info a per-virtual-interface structure for the
rare case where we have multiple virtual stations associated to the same
AP or for example WDS links.
Working through the code I notice that struct sta_info has a "dev"
pointer (which I will change to "sdata"), but as far as I can tell
nothing guarantees that we don't do sta_info_get(), then down the
interface, and then try to dereference sta_info->dev.
I see two ways to avoid this:
(1) in sta_info_flush(), wait until each sta is actually released,
don't just put it
(2) with each sta_info_get() also do a dev_hold()
