Subject: lib: parser: fix match_wildcard to correctly handle trailing stars
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=d01684a2f0f84a3d4210bb76a7ca62c4253b8e93;p=thirdparty%2Fkernel%2Fstable.git

lib: parser: fix match_wildcard to correctly handle trailing stars

This fixes a bug in match_wildcard that incorrectly handles trailing
asterisks.  For example, `match_wildcard("abc**", "abc")` must return
true, but it returns false.
