usbtest: Disable gcc9 -Waddress-of-packed-member
Disable the -Wadress-of-packaed-member diagnostic for the grub_usb_get_string function since the result is false postive. The descstrp->str is found to be aligned in the buffer allocated for 'struct grub_usb_desc_str'. [ 229s] ../../grub-core/commands/usbtest.c: In function 'grub_usb_get_string': [ 229s] ../../grub-core/commands/usbtest.c:104:58: error: taking address of packed member of 'struct grub_usb_desc_str' may result in an unaligned pointer value [-Werror=address-of-packed-member] [ 229s] 104 | *grub_utf16_to_utf8 ((grub_uint8_t *) *string, descstrp->str, [ 229s] | ~~~~~~~~^~~~~ Signed-off-by: Michael Chang <mchang@suse.com> Reviewed-by: Daniel Kiper <daniel.kiper@oracle.com>
