Fix:
util/btf.c: In function '__btf_type__find_member_by_name':
util/btf.c:19:43: error: comparison of integer expressions of different signedness: 'int' and '__u32' {aka 'unsigned int'} [-Werror=sign-compare]
19 | for (i = 0, m = btf_members(t); i < btf_vlen(t); i++, m++) {
| ^
builtin-trace.c: In function 'syscall_arg__strtoul_btf_enum':
builtin-trace.c:967:27: error: comparison of integer expressions of different signedness: 'int' and '__u32' {aka 'unsigned int'} [-Werror=sign-compare]
967 | for (int i = 0; i < btf_vlen(bt); ++i, ++be) {
| ^
by making the variable the same type as the function.
Committer note:
Add an extra hunk from Alan Maguire, fixing btf_enum_scnprintf().
