From 4796efdd16a8066919a3ff479e0bbc14bac816ff Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Fri, 16 Dec 2022 13:41:12 +0200 Subject: [PATCH] thunderbolt: Ignore data CRC mismatch for USB4 routers This is also something not always updated after the DROM contents itself so issue warning but continue parsing it as we do for pre-USB4 DROMs too.
