scsi: message: fusion: struct _CONFIG_PAGE_IOC_2: Replace 1-element array with flexible array
Replace the deprecated[1] use of a 1-element array in struct
_CONFIG_PAGE_IOC_2 with a modern flexible array.
Additionally add __counted_by annotation since RaidVolume is only ever
accessed from loops controlled by NumActiveVolumes:
lsi/mpi_cnfg.h: CONFIG_PAGE_IOC_2_RAID_VOL RaidVolume[] __counted_by(NumActiveVolumes); /* 0Ch */
mptbase.c: for (i = 0; i < pIoc2->NumActiveVolumes ; i++)
mptbase.c: pIoc2->RaidVolume[i].VolumeBus,
mptbase.c: pIoc2->RaidVolume[i].VolumeID);
mptsas.c: for (i = 0; i < ioc->raid_data.pIocPg2->NumActiveVolumes; i++) {
mptsas.c: RaidVolume[i].VolumeID) {
mptsas.c: RaidVolume[i].VolumeBus;
mptsas.c: for (i = 0; i < ioc->raid_data.pIocPg2->NumActiveVolumes; i++) {
mptsas.c: ioc->raid_data.pIocPg2->RaidVolume[i].VolumeID, 0);
mptsas.c: ioc->raid_data.pIocPg2->RaidVolume[i].VolumeID);
mptsas.c: ioc->raid_data.pIocPg2->RaidVolume[i].VolumeID, 0);
mptsas.c: for (i = 0; i < ioc->raid_data.pIocPg2->NumActiveVolumes; i++) {
mptsas.c: if (ioc->raid_data.pIocPg2->RaidVolume[i].VolumeID ==
mptsas.c: for (i = 0; i < ioc->raid_data.pIocPg2->NumActiveVolumes; i++)
mptsas.c: if (ioc->raid_data.pIocPg2->RaidVolume[i].VolumeID == id)
mptspi.c: for (i=0; i < ioc->raid_data.pIocPg2->NumActiveVolumes; i++) {
mptspi.c: if (ioc->raid_data.pIocPg2->RaidVolume[i].VolumeID == id) {
No binary differences are present after this conversion.
