Re: [PATCH] net: wireless: b43: Avoid possible double calls to b43_one_core_detach()

Jia-Ju Bai [off-list ref] writes:

In b43_request_firmware(), when ieee80211_register_hw() fails,
b43_one_core_detach() is called. In b43_bcma_remove() and
b43_ssb_remove(), b43_one_core_detach() is called again. In this case, 
null-pointer dereferences and double-free problems can occur when 
the driver is removed.

To fix this bug, the call to b43_one_core_detach() in
b43_request_firmware() is deleted.

This bug is found by a runtime fuzzing tool named FIZZER written by us.

You can use just "b43:" as prefix, no need to have "net:" nor
"wireless:" in the title. I'll fix it this time, but please use correct
style in the future.
