This fixes bug that could cause WARNING on every add_key/del_key call. It also replaces WARNING with a simple message. They may still occur e.g. on station going out of range and A-MPDU stall in the firmware. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

Subject: [PATCH] brcmfmac: replace WARNING on timeout with a simple error

Even with timeout increased to 950 ms we get WARNINGs from time to time.
|
|
It mostly happens on A-MPDU stalls (e.g. when station goes out of
|
|
range). It may take up to 5-10 secods for the firmware to recover and
|
|
for that time it doesn't process packets.
|
|
|
|
It's still useful to have a message on time out as it may indicate some
|
|
firmware problem and incorrect key update. Raising a WARNING however
|
|
wasn't really that necessary, it doesn't point to any driver bug anymore
|
|
and backtrace wasn't much useful.
