From: Juuso Oikarinen <juuso.oikarinen@xxxxxxxxx> Due to legacy reason, dating back to when the wl1251 and wl1271 still were a unified driver, some work-structures are initialized on hardware startup. The hardware recovery code creates a scenario in which it is possible for a workstruct to be re-initialized while the work-function itself is running, which causes a kernel WARNing and a subsequent reboot. To remedy this, move the work initialization calls to the hw allocation, which is the logically correct place for them anyway.
