Ingo,
when you added the locking correctness validator code in commit fbb9ce95, you exported lockdep_init_map() with EXPORT_SYMBOL_GPL. This choice is causing a problem with the latest version of Broadcom's hybrid wl driver. Although I do not agree with their policies regarding drivers with binary blobs, there are some devices such as the BCM43228 (14e4:4359) for which no open-source driver is yet available. As a result, owners of such devices are forced to use solutions such as ndiswrapper, which is worse than using wl.
would you accept the following patch?
