[libvirt] [PATCH 1/2] util: ignore -Wcast-align in virNetlinkDumpCommand
Similar to commit b202c39 ignore the warning that breaks the build
with clang:
util/virnetlink.c:365:52: error: cast from 'char *' to 'struct nlmsghdr
*'
increases required alignment from 1 to 4 [-Werror,-Wcast-align]
for (msg = resp; NLMSG_OK(msg, len); msg = NLMSG_NEXT(msg, len)) {
^~~~~~~~~~~~~~~~~~~~
/usr/include/linux/netlink.h:87:7: note: expanded from macro 'NLMSG_NEXT'
(struct nlmsghdr*)(((char*)(nlh)) + NLMSG_ALIGN((nlh)->nlmsg_len)))
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
