Just a heads up: [No, I haven't forgotten about this] While my patches certainly caused some "noise" @ lkml. So far there hasn't been any progress about request_firmware_nowait. I'll keep at it but it could take a while longer... In the meantime: I think we could get atleast fix p54pci and friends. Larry, what do you say? And John: Would you accept the patches? even though they need the listed pcmcia and firmware_class fixes in order to work [without those, on resume you get WARNINGs and an you need to reload the driver/replug the device] Regards, Chr -- 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
