Merge tag 'libcrypto-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux
Pull crypto library fix from Eric Biggers:
"Fix an uninitialized variable in the s390 optimized SHA-1 and SHA-2.
Note that my librarification changes also fix this by greatly
simplifying how the s390 optimized SHA code is integrated. However, we
need this separate fix for 6.16 and older versions"
