staging: brcm80211: bugfix for softmac crash on multi cpu configurations
commit 6a3be6e6e7feb4cb35275475d6a863b748d59cc3 upstream
Solved a locking issue that resulted in driver crashes with the 43224 and 43225
chips. The problem has been reported on several fora. Root cause was two fold:
hardware was being manipulated by two unsynchronized threads, and a scan
operation could interfere with an ongoing dynamic calibration process. Fix was
to invoke a lock on wl_ops_config() operation and to set internal flags when a
scan operation is started and stopped.
Please add this to the staging-linus branch.
