[01/10,next] scsi: aacraid: Replace one-element array with flexible-array member
Commit Message
Replace one-element array with flexible-array member in struct
aac_ciss_phys_luns_resp.
This results in no differences in binary output.
Issue found with the help of Coccinelle and audited and fixed,
manually.

I think the Subject was cut off (it lacks mention of
aac_ciss_phys_luns_resp, where as the other patches mention the target
struct).
