How to enable CONFIG_MTD_PSTORE option in config file?

Hi Intel Kernel Team,

I try to compile new version with 5.10 branch.
But i notice one issue with MTD config option.
I can't enable it. And if I write it to the .config configuration file, it disappears during make oldconfig.

CONFIG_MTD_PSTORE=m

1. with issue: linux-intel-lts, branch: 5.10/yocto, version: 5.10.52, sha: 2241189
2. with not issue: linux-intel-lts, branch: 5.10/yocto, version: 5.10.47, sha: 3ebd33d

Is a kernel regression?

Have a good day.

I think this option is no longer necessary.
I've seen in newer kernel versions that this replicated. 5.12.17
In this case I will no longer use this option when configuring the kernel.
