[Qemu-devel] [PATCH 078/113] pc-bios/s390-ccw: struct tpi_info must be declared as aligned(4) |

From: Thomas Huth <address@hidden>
I've run into a compilation error today with the current version of GCC 8:
In file included from s390-ccw.h:49,
from main.c:12:
cio.h:128:1: error: alignment 1 of 'struct tpi_info' is less than 4
[-Werror=packed-not-aligned]
} __attribute__ ((packed));
^
cc1: all warnings being treated as errors
Since the struct tpi_info contains an element ("struct subchannel_id schid")
which is marked as aligned(4), we've got to mark the struct tpi_info as
aligned(4), too.
