You should probably keep this for development purposes, but it will break if your code is built into the kernel. The working model we've adopted to solve this is to use request_firmware_nowait() in probe, and then only continue doing work when the firmware loading returns (and then register with mac80211 etc) johannes -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
