I can work on this. Logically, there can be two patches- 1) BLK tag
support 2) changes in calling convention of return_cmd (this patch will
revert the changes done by patch- 90dc9d9 megaraid_sas : MFI MPT linked
list corruption fix).
So patch #2 will be very much dependent on patch #1. If someone applies
patch #2 without applying patch#1, then bug fixed by  "90dc9d9
megaraid_sas : MFI MPT linked list corruption fix " will be exposed again.
That's why I club these two patches in a single patch. Regarding debug
prints, that can be removed.
