[PATCH 6.1 41/85] mmc: sdhci-acpi: Fix Lenovo Yoga Tablet 2 Pro 1380 sdcard slot not working

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hans de Goede <hdegoede@redhat.com>

commit f3521d7cbaefff19cc656325787ed797e5f6a955 upstream.

The Lenovo Yoga Tablet 2 Pro 1380 sdcard slot has an active high cd pin
and a broken wp pin which always reports the card being write-protected.

Add a DMI quirk to address both issues.
