[PATCH 6.9 048/157] mmc: sdhci-acpi: Disable write protect detection on Toshiba WT10-A

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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

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

From: Hans de Goede <hdegoede@xxxxxxxxxx>

commit ef3eab75e17191e5665f52e64e85bc29d5705a7b upstream.

On the Toshiba WT10-A the microSD slot always reports the card being
write-protected, just like on the Toshiba WT8-B.

Add a DMI quirk to work around this.
