net/wireless: add COUNTRY to to regulatory device uevent
Regulatory devices issue change uevents to inform userspace of a need to call the crda tool; however these can often be sent before udevd is running, and were not previously included in the results of udevadm trigger (which requests a new change event using the /uevent attribute of the sysfs object). Add a uevent function to the device type which includes the COUNTRY information from the last request if it has yet to be processed, the case of multiple requests is already handled in the code by checking whether an unprocessed one is queued in the same manner and refusing to queue a new one. The existing udev rule continues to work as before. Signed-off-by:Scott James Remnant <keybuk@google.com> Acked-By:
