Kees Cook de80fe29ab 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.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
