usb: storage: make const arrays static, reduces object code size
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 Signed-off-by: Colin Ian King <colin.king@canonical.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
