scsi: qla2xxx: edif: Fix clang warning
[ Upstream commit 2f5fab1b6c3a8efc93ba52c28539c45a8d0142ad ]
clang warning:
drivers/scsi/qla2xxx/qla_edif_bsg.h:93:12: warning: field remote_pid
within 'struct app_pinfo_req' is less aligned than 'port_id_t' and is
usually due to 'struct app_pinfo_req' being packed, which can lead to
unaligned accesses [-Wunaligned-access]
port_id_t remote_pid;
^
2 warnings generated.
Remove u32 field in remote_pid to silence warning.
