Subject[PATCH] usb: storage: make const arrays static, reduces object code size
Date
From: Colin Ian King <colin.king@canonical.com>

Don't populate const arrays on the stack, instead make them
static. Makes the object code smaller by over 1070 bytes:

Before:
text data bss dec hex filename
3505 880 0 4385 1121 drivers/usb/storage/option_ms.o

After:
text data bss dec hex filename
2269 1040 0 3309 ced drivers/usb/storage/option_ms.o
