Subject: [PATCH] brcmfmac: print firmware messages after a firmware crash

Normally firmware messages are printed with debugging enabled only. It's
|
||
|
|
a good idea as firmware may print a lot of messages that normal users
|
||
|
|
don't need to care about.
|
||
|
|
|
||
|
|
However, on firmware crash, it may be very helpful to log all recent
|
||
|
|
messages. There is almost always a backtrace available as well as rought
|
||
|
|
info on the latest actions/state.
