1207 * The EFI spec defines this as efi_guid_t.

1209 * clang with -Wunaligned-access
1210 * warning: field guid within 'struct efi_hii_keyboard_layout' is less
1211 * aligned than 'efi_guid_t' and is usually due to
1212 * 'struct efi_hii_keyboard_layout' being packed, which can lead to
1213 * unaligned accesses
1214 *
1215 * GCC with -Wpacked-not-aligned -Waddress-of-packed-member
1216 * 'efi_guid_t' offset 2 in 'struct efi_hii_keyboard_layout'
1217 * isn't aligned to 4
1218 *
1219 * Removing the alignment from efi_guid_t is not an option, since
1220 * it is also used in non-packed structs and that would break
1221 * calculations with offsetof
1222 *
1223 * This is the only place we get a report for. That happens because
1224 * all other declarations of efi_guid_t within a packed struct happens
1225 * to be 4-byte aligned. i.e a u32, a u64 a 2 * u16 or any combination
1226 * that ends up landing efi_guid_t on a 4byte boundary precedes.
1227 *
1228 * Replace this with a 1-byte aligned counterpart of b[16]. This is a
1229 * packed struct so the memory placement of efi_guid_t should not change
