James" This series refactors the FSI client device drivers. It adds a number of fixes discovered from bugs over the past several months. Most critically, it fixes various race conditions in the unbind/remove pathway of the occ-hwmon, occ, and sbefifo drivers. Changes since v1: * split into multiple patches. * add memory management patch. Edward A.
