Bluetooth: btrtl: Make array extension_sig static, shrinks object size
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) Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
