linux-6.6/tools/perf/util/bpf_map.c:50:8: style: Suspicious condition

[David Binderman <dcb314@xxxxxxxxxxx>]

Hello there,

Static analyser cppcheck says:

linux-6.6/tools/perf/util/bpf_map.c:50:8: style: Suspicious condition (assignment + comparison); Clarify expression with parentheses. [clarifyCondition]

Source code is

    while ((err = bpf_map_get_next_key(fd, prev_key, key) == 0)) {

Suggest new code:

    while ((err = bpf_map_get_next_key(fd, prev_key, key)) == 0) {

Regards

David Binderman
