Subject: [PATCH][next] scsi: bfa: Replace one-element array with
flexible-array member
One-element arrays are deprecated, and we are replacing them with flexible
array members instead. So, replace one-element array with flexible-array
member in struct fdmi_attr_s.
Important to mention is that doing a build before/after this patch results
in no binary output differences.
This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines
on memcpy() and help us make progress towards globally enabling
-fstrict-flex-arrays=3 [1].
