 Note for people who use request_firmware_nowait():
 You are required to do your own synchronization after you call
 request_firmware_abort() in order to continue unloading the
 module. The example synchronization code shows below:
 
 while (THIS_MODULE  module_refcount(THIS_MODULE))
   msleep(20);

This is _so_ asking for people to get it wrong, it is not funny :-(

 That's why modern systems require signed firmware updates.

Linux doesn't.  Is someone working on adding signature support to the
