Merge tag 'zstd-linus-v6.2' of https://github.com/terrelln/linux

Pull zstd updates from Nick Terrell:
 "Update the kernel to upstream zstd v1.5.2 [0]. Specifically to the tag
  v1.5.2-kernel [1] which includes several cherrypicked fixes for the
  kernel on top of v1.5.2.

  Excepting the MAINTAINERS change, all the changes in this can be
  generated by:

    git clone https://github.com/facebook/zstd
    cd zstd/contrib/linux-kernel
    git checkout v1.5.2-kernel
    LINUX=/path/to/linux/repo make import

  Additionally, this includes several minor typo fixes, which have all
  been fixed upstream so they are maintained on the next import"
