Subject: [PATCH] EDAC/mce_amd: Add missing long names for SMCA bank types
Date: Fri,  9 Oct 2026 10:04:24 +0800	[thread overview]
Message-ID: <20261009020447.90758-2-weiguixiong@bytedance.com> (raw)

Commit 47b744ea5e3c ("x86/MCE/AMD: Add new MA_LLC, USR_DP,
and USR_CP bank types") added three SMCA bank types after the bank long
names had been moved to the MCE decoder.

The new types were added to the enum, short-name table, and HWID/McaType
mapping, but not to smca_long_names[]. As a result, an error from any of
these banks is logged with "(null)" in place of the bank name.

Add the missing long names.

Fixes: 47b744ea5e3c ("x86/MCE/AMD: Add new MA_LLC, USR_DP, and USR_CP bank types")
