usb: gadget: udc: renesas_usb3: make const array max_packet_array static
Don't populate the const array max_packet_array on the stack, instead make it static. Makes the object code smaller by over 90 bytes: Before: text data bss dec hex filename 34337 5612 128 40077 9c8d renesas_usb3.o After: text data bss dec hex filename 34149 5708 128 39985 9c31 renesas_usb3.o (gcc version 7.2.0 x86_64) Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
