Due to the OCC communication design with a shared SRAM area,
checkum errors are expected due to corrupted buffer from OCC
communications with other system components. Therefore, use a
unique errno for checksum failures and retry the command twice
in that case.

Changes since v1:
 - Refactor the retry loop

Eddie James (2):
  fsi: occ: Fix checksum failure mode
  hwmon (occ): Retry for checksum failure
