   4 Subject: scsi: smartpqi: increase fw status register read timeout
   5
   6 [ Upstream commit 65111785acccb836ec75263b03b0e33f21e74f47 ]
   7
   8 Problem:
   9  - during the driver initialization, driver will poll fw
  10    for KERNEL_UP in a 30 seconds timeout.
  11
  12  - if the firmware is not ready after 30 seconds,
  13    driver will not be loaded.
  14
  15 Fix:
  16  - change timeout from 30 seconds to 3 minutes.
