linux/drivers/hid/usbhid/hid-core.c
Jiri Kosina 48b4554aca USB HID: consolidate vendor/product ids 
The vendor/product IDs for the purposes of hid_blacklist got
scathered around the hid-core.c in a rather random way over the
time.

Move all the related definitions at the beginning of the file,
and make them sorted again. Sort also hid_blacklist properly.
