Subject: tools/cgget: free cgrp_list array
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4436ad9946a42db61bb39ba0fb975faee829cbfd;p=thirdparty%2Flibcgroup.git

tools/cgget: free cgrp_list array

Even after fixing per-controller leaks, ASan still reported an 8 byte
leak on exit:

    Direct leak of 8 byte(s) in 1 object(s) allocated from:
        #0 0x... in __interceptor_realloc
        #1 create_cgrp (<libcgroup-source>/src/tools/cgget.c:76)

main() freed each struct cgroup * in cgrp_list but never released the
pointer array itself, so the final realloc() stayed live. After freeing
the entries, free cgrp_list too. This fix the sanitizer warning.
