This was unsafe > because matching is not an atomic operation with probing a driver. If > two or more drivers are attempted to be matched to a driver at the > same time, then the cached matching entry pointer could get > overwritten. > > This patch reverts the of_match cache pointer and reworks all users to > call of_match_device() directly instead. > > Signed-off-by: Grant Likely <grant.likely@xxxxxxxxxxxx> Tested on SunBlade2500 and Niagara2+ Acked-by: David S.
