Subject: kdb: Replace strncmp with str_has_prefix
X-Git-Tag: v5.15~5478^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=635714312e6a515de2e78e74bf8d5b10593a4dbf;p=platform%2Fkernel%2Flinux-starfive.git

kdb: Replace strncmp with str_has_prefix

strncmp(str, const, len) is error-prone.
We had better use newly introduced
str_has_prefix() instead of it.
