stable inclusion from stable-5.10.51 commit 5ced01c0e8552b98f4688a2a773bd01006bedc15 bugzilla: 175263 https://gitee.com/openeuler/kernel/issues/I4DT6F
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
commit 94ee6782e045645abd9180ab9369b01293d862bd upstream.
On the Toshiba Encore 2 WT8-B the microSD slot always reports the card being write-protected even though microSD cards do not have a write-protect switch at all.
Add a new DMI_QUIRK_SD_NO_WRITE_PROTECT quirk entry to sdhci-acpi.c's DMI quirk table for this.
