Subject: namei: fix const qualifier warning in readlink_to_namei
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e318417f00982bf496fd2359853b07ada3e3c544;p=thirdparty%2Futil-linux.git

namei: fix const qualifier warning in readlink_to_namei

Fix const qualifier discarded warning in readlink_to_namei().
This warning is reported by gcc 15 which defaults to the C23 standard.

The strrchr() function returns a pointer into a const string, so the
receiving variable must be declared as const char *.
