This terminal 1-length variable array can be directly converted into a C99
flexible array member.
As all users of MPI2_CONFIG_PAGE_SASIOUNIT_0 (Mpi2SasIOUnitPage0_t) either
calculate its size without depending on its sizeof() or do not use
PhyData[], no further source changes are required:
- mpt3sas_config.c:mpt3sas_config_get_number_hba_phys() fetches a
Mpi2SasIOUnitPage0_t for itself, but does not use PhyData[].
- mpt3sas_config.c:mpt3sas_config_get_sas_iounit_pg0() fetches a
Mpi2SasIOUnitPage0_t into a caller-provided buffer, and may fetch and
write PhyData[] into that buffer depending on its sz argument. Its
callers:
- mpt3sas_scsih.c:_scsih_update_vphys_after_reset(),
mpt3sas_scsih.c:_scsih_get_port_table_after_reset(),
mpt3sas_scsih.c:_scsih_sas_host_refresh(),
mpt3sas_scsih.c:_scsih_sas_host_add(), and
mpt3sas_transport.c:_transport_phy_enable() all calculate sz
independently of sizeof(Mpi2SasIOUnitPage0_t) and allocate a
suitable buffer before calling mpt3sas_config_get_sas_iounit_pg0()
and using PhyData[].

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 Restructured Text 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.
