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.
