Subject: [PATCH] crypto: octeontx2 - uninitialized variable in kvf_limits_store()
Git-commit: 0ea275df84c389e910a3575a9233075118c173ee
Patch-mainline: v5.17-rc1
References: git-fixes
If kstrtoint() fails then "lfs_num" is uninitialized and the warning
doesn't make any sense. Just delete it.
Fixes: 8ec8015a3168 ("crypto: octeontx2 - add support to process the crypto request")
