Hi reviewers,
I suggest to backport a commit to Linux kernel-5.10 and 6.6 stable tree.

mmc: core: Add wp_grp_size sysfs node The eMMC card can be set into write-protected mode to prevent data from being accidentally modified or deleted. Wp_grp_size (Write Protect Group Size) refers to an attribute of the eMMC card, used to manage write protection and is the CSD register [36:32] of the eMMC device. Wp_grp_size (Write Protect Group Size) indicates how many eMMC blocks are contained in each write protection group on the eMMC card.
To allow userspace easy access of the CSD register bits, let's add sysfs node "wp_grp_size".

Why? What bug does this fix?
Dear mailto:sashal@kernel.org,
This patch is not a bug fix. This patch is to add the sysfs node of mmc: write protection related, the detailed description is as follows:

Wp_grp_size (Write Protect Group Size) refers to an attribute of the eMMC card, used to manage write protection and is the CSD register [36:32] of the eMMC device.
