Analyze and fix the following issue in the Linux kernel code: staging: brcm80211: bugfix for softmac crash on multi cpu configurations
Problem Details: 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. ...
