Kees Cook 70631322db scsi: message: fusion: struct _CONFIG_PAGE_IOC_3: Replace 1-element array with flexible array
Replace the deprecated[1] use of a 1-element array in struct
_CONFIG_PAGE_IOC_3 with a modern flexible array.

Additionally add __counted_by annotation since PhysDisk is only ever
accessed via a loops bounded by NumPhysDisks:

lsi/mpi_cnfg.h:    IOC_3_PHYS_DISK             PhysDisk[] __counted_by(NumPhysDisks); /* 08h */
mptscsih.c:	for (i = 0; i < ioc->raid_data.pIocPg3->NumPhysDisks; i++) {
mptscsih.c:		if ((id == ioc->raid_data.pIocPg3->PhysDisk[i].PhysDiskID) &&
mptscsih.c:		    (channel == ioc->raid_data.pIocPg3->PhysDisk[i].PhysDiskBus)) {
mptscsih.c:	for (i = 0; i < ioc->raid_data.pIocPg3->NumPhysDisks; i++) {
mptscsih.c:		    ioc->raid_data.pIocPg3->PhysDisk[i].PhysDiskNum);
mptscsih.c:		    ioc->raid_data.pIocPg3->PhysDisk[i].PhysDiskNum,
mptscsih.c:	for (i = 0; i < ioc->raid_data.pIocPg3->NumPhysDisks; i++) {
mptscsih.c:		if ((id == ioc->raid_data.pIocPg3->PhysDisk[i].PhysDiskID) &&
mptscsih.c:		    (channel == ioc->raid_data.pIocPg3->PhysDisk[i].PhysDiskBus)) {
mptscsih.c:			rc = ioc->raid_data.pIocPg3->PhysDisk[i].PhysDiskNum;
mptscsih.c:	for (i = 0; i < ioc->raid_data.pIocPg3->NumPhysDisks; i++) {
mptscsih.c:		    ioc->raid_data.pIocPg3->PhysDisk[i].PhysDiskNum);
mptscsih.c:		    ioc->raid_data.pIocPg3->PhysDisk[i].PhysDiskNum,

No binary differences are present after this conversion.

README

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.
