Subject[PATCH] Bluetooth: btrtl: make array extension_sig static, shrinks object size
Date
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 59 bytes:

Before:
text data bss dec hex filename
14366 4920 0 19286 4b56 linux/drivers/bluetooth/btrtl.o

After:
text data bss dec hex filename
14243 4984 0 19227 4b1b linux/drivers/bluetooth/btrtl.o

(gcc version 8.2.0 x86_64)
