On m68k:
drivers/nvme/host/tcp.c: In function ‘nvme_tcp_init_module’:
include/linux/compiler_types.h:397:38: error: call to ‘__compiletime_assert_723’ declared with attribute error: BUILD_BUG_ON failed: sizeof(struct nvme_tcp_term_pdu) != 24
Indeed, on m68k the minimum alignment is 2 bytes, not 4 bytes, thus
triggering the check added in commit 7e87965d3807ab1f ("nvme-tcp: add
nvme-tcp pdu size build protection"), and indicating that NVMe over
Fabrics TCP on m68k must be incompatible with other platforms.
Fix this by adding explicit padding.
