Dear gregkh@linuxfoundation.org,
I'm very sorry for the trouble, here's the update:
From f033ef0bfb29cd413d10aba860ce8d178cc314e2 Mon Sep 17 00:00:00 2001 From: Mengqi Zhang mailto:mengqi.zhang@mediatek.com Date: Mon, 25 Dec 2023 17:38:40 +0800 Subject: [PATCH] mmc: core: Add HS400 tuning in HS400es initialization
commit 77e01b49e35f24ebd1659096d5fc5c3b75975545 upstream
During the initialization to HS400es stage, add a HS400 tuning flow as an optional process. For Mediatek IP, the HS400es mode requires a specific tuning to ensure the correct HS400 timing setting.

Better, thanks, but your email client still did odd things to the email addresses.
I've fixed this up by hand, but please, be more careful next time...
