being trailing arrays declared with [] as the last member of a
struct. Unbounded trailing arrays declared with [1] are common in
mpt3sas, which is causing spurious warnings to appear in some
situations, e.g. when more than one physical disk is connected:

  UBSAN: array-index-out-of-bounds in drivers/scsi/mpt3sas/mpt3sas_scsih.c:6810:36
  index 1 is out of range for type 'MPI2_SAS_IO_UNIT0_PHY_DATA [1]'

which relates to this unbounded array access:

  port_id = sas_iounit_pg0->PhyData[i].Port;

and is just one example of 10 similar warnings currently occurring for
me during boot.

This series converts most trailing arrays declared with [1] in mptsas
into proper C99 flexible array members. Those that are not unbounded
and really are fixed-length arrays of length 1 are left alone.

I didn't find any conversions that required further source edits
besides changing [1] to [], and everything seems to work with my
SAS2008-based add-in card, but please look things over in case I
missed something subtle.

Rounding out the series are some opportunistic cleanups.

The only dependency is that patch 7 ("Use struct_size() for struct
size calculations") depends on patches 3-5.

strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string

This pattern of strncpy(dest, src, strlen(src)) is extremely bug-prone.
This pattern basically never results in NUL-terminated destination
strings unless `dest` was zero-initialized. The current implementation
may be accidentally correct as tw_dev is zero-allocated via:

host = scsi_host_alloc(&driver_template, sizeof(TW_Device_Extension));
        ...
tw_dev = shost_priv(host);

... wherein scsi_host_alloc() zero-allocates host:

        shost = kzalloc(sizeof(struct Scsi_Host) + privsize, GFP_KERNEL);

Also, further suggesting this change is worthwhile is another strscpy()
usage in 3w-9xxx.c:

strscpy(tw_dev->tw_compat_info.driver_version, TW_DRIVER_VERSION,
sizeof(tw_dev->tw_compat_info.driver_version));

Considering the above, a suitable replacement is strscpy() [2] due to
the fact that it guarantees NUL-termination on the destination buffer

As all users of MPI2_CONFIG_PAGE_IO_UNIT_8 (Mpi2IOUnitPage8_t) do not use
Sensor[], no further source changes are required to accommodate its reduced
sizeof():

 - mpt3sas_config.c:mpt3sas_config_get_iounit_pg8() fetches a
   Mpi2IOUnitPage8_t into a caller-provided buffer, assuming
   sizeof(Mpi2IOUnitPage8_t) as the buffer size. It has one caller:

   - mpt3sas_base.c:_base_static_config_pages() passes the address of the
     Mpi2IOUnitPage8_t iounit_pg8 member of the per-adapter struct (struct
     MPT3SAS_ADAPTER *ioc) as the buffer. The assumed buffer size is
     therefore correct.

     However, the only subsequent use in mpt3sas of the thus populated
     ioc->iounit_pg8 is a little further on in the same function, and this
     use does not involve ioc->iounit_pg8.Sensor[].

     Note that iounit_pg8 occurs in the middle of the per-adapter struct,
     not at the end. The per-adapter struct is extensively used throughout
     mpt3sas even if its iounit_pg8 member isn't, resulting in an
     especially large amount of noise when comparing binary changes
     attributable to this commit.

spi: Fix null dereference on suspend

active during a system suspend. This can cause a null pointer
dereference exception to occur when the system resumes.

Example order of events leading to the exception:
1. spi_sync() calls __spi_transfer_message_noqueue() which sets
   ctlr->cur_msg
2. Spi transfer begins via spi_transfer_one_message()
3. System is suspended interrupting the transfer context
4. System is resumed
6. spi_controller_resume() calls spi_start_queue() which resets cur_msg
   to NULL
7. Spi transfer context resumes and spi_finalize_current_message() is
   called which dereferences cur_msg (which is now NULL)

Wait for synchronous transfers to complete before suspending by
