Subject: crypto: octeontx2 - uninitialized variable in kvf_limits_store()
X-Git-Tag: v6.1-rc5~2292^2~85
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0ea275df84c389e910a3575a9233075118c173ee;p=platform%2Fkernel%2Flinux-starfive.git

crypto: octeontx2 - uninitialized variable in kvf_limits_store()

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")
