[PATCH 1/1] cxl/events: Fix Trace DRAM Event Record

[<shiju.jose@huawei.com>]

From: Shiju Jose <shiju.jose@huawei.com>

CXL spec rev 3.0 section 8.2.9.2.1.2 defines the DRAM Event Record.

Fix decode memory event type field of DRAM Event Record.
For e.g. if value is 0x1 it will be reported as an Invalid Address
(General Media Event Record - Memory Event Type) instead of Scrub Media
ECC Error (DRAM Event Record - Memory Event Type) and so on.

Fixes: 2d6c1e6d60ba ("cxl/mem: Trace DRAM Event Record")
Signed-off-by: Shiju Jose <shiju.jose@huawei.com>

Updates for event records in CXL spec r3.1 will follow shortly.
