5.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Hans de Goede <hdegoede@xxxxxxxxxx> 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.
