Subject: [PATCH v4 08/20] EDAC/synopsys: Drop internal CE and UE counters
Date:   Wed, 20 Sep 2023 22:10:32 +0300
Message-ID: <20230920191059.28395-9-fancer.lancer@gmail.com>

First of all these counters aren't exposed anyhow from the driver.
Secondly the EDAC core already tracks the total amount of the correctable
and uncorrectable errors (see mem_ctl_info.{ce_mc,ue_mc} fields usage).
Drop the useless internal counters then for good.

Signed-off-by: Serge Semin <fancer.lancer@gmail.com>

Changelog v4:
- Drop redundant empty line.
- Drop private counters access from the check_errors() method too.
