From: Colin Ian King <colin.king@canonical.com>
Don't populate the array extension_sig on the stack but instead make it static. Makes the object code smaller by 75 bytes:
Before: text data bss dec hex filename 14325 4920 0 19245 4b2d drivers/bluetooth/btrtl.o
After: text data bss dec hex filename 14186 4984 0 19170 4ae2 drivers/bluetooth/btrtl.o
(gcc version 8.2.0 x86_64)
