Hi Johannes, I am looking into implementing rfkill into our brcm80211 open-source driver. Our driver detects disable switch by an interrupt, but switching back does not give an interrupt. For the latter I wanted to use the rfkill_poll callback and wiphy_rfkill_start_polling. However, I tried a wiphy_rfkill_stop_polling in the rfkill_poll callback when rf is unblocked, and this resulted in a system hang. So I moved the wiphy_rfkill_stop_polling to the start callback. Does that make sense or is there another way you would recommend? Gr.
