Subject: partx: fix const qualifier warning in get_max_partno
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4c94ce5d05d97420df7a512bbbaee8c4017414ae;p=thirdparty%2Futil-linux.git

partx: fix const qualifier warning in get_max_partno

Fix const qualifier discarded warning in get_max_partno().
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 *.
