Subject[PATCH] Bluetooth: bpa10x: make array 'req' static, shrinks object size
Date
From: Colin Ian King <colin.king@canonical.com>

Don't populate the const read-only array 'req' on the stack but instead
make it static. Makes the object code smaller by over 40 bytes:

Before:
text data bss dec hex filename
8497 3408 128 12033 2f01 linux/drivers/bluetooth/bpa10x.o

After:
text data bss dec hex filename
8366 3496 128 11990 2ed6 linux/drivers/bluetooth/bpa10x.o

(gcc version 7.2.0 x86_64)
