Subject: [PATCH 09/19] scsi: hisi_sas: use array for v2 hw AXI errors
From: Shiju Jose <shiju.jose@...wei.com>
The code to print AXI errors in v2 hw driver is
repetitive.
This patch condenses the code by looping an array of
errors.
Also, a formatting error in one_bit_ecc_errors[] and
multi_bit_ecc_errors[] is fixed.
