This patch (i. e. 38a9a5121c3b ("lib/crc32: make crc32c() go directly to lib")) solves actual bug I found in practice. So, please, backport it to stable kernels.

Oops. I just noticed that this patch removes module "libcrc32c". And this breaks build for Debian kernel v6.12.48. Previously I tested minimal build using "make localmodconfig". Now I tried full build of Debian kernel using "dpkg-buildpackage". And it failed, because some of Debian files reference "libcrc32c", which is not available.

So, please, don't backport this patch to stable kernels. I'm sorry.
