Doorbell and Host diagnostic registers could return 0 even
after 3 retries and that leads to occasional resets of the
controllers, hence increased the retry count to thirty.

v1->v2:
-added a new patch for volatile as suggested by Greg KH.
-renamed macro as suggested by Damien Le Moal.

v2->v3:
-Modified patch description with more details.

Ranjan Kumar (2):
  Perform additional retries if Doorbell read returns 0
  mpt3sas: Removing volatile qualifier
