This series aims to replace one-element arrays with flexible-array
members in multiple structures in drivers/scsi/aacraid/aacraid.h.

This helps with the ongoing efforts to globally enable -Warray-bounds
and get us closer to being able to tighten the FORTIFY_SOURCE routines
on memcpy().

These issues were found with the help of Coccinelle and audited and fixed,
manually.

I'd like to reorganize this series so that all the conversions are
first, and then struct_size() additions are at the end. That way, if
desired, the conversions can land as fixes to turn the Clang builds
green again.


OK; I can make that happen. :)
