When building selftests/vDSO with clang the following warning shows up:
clang -std=gnu99 -Wno-pointer-sign vdso_test_gettimeofday.c parse_vdso.c \ -o /tmp/kselftest/vDSO/vdso_test_gettimeofday parse_vdso.c:65:9: warning: using the result of an assignment as a condition without parentheses [-Wparentheses] if (g = h & 0xf0000000) ~~^~~~~~~~~~~~~~~~
Rework to a parentheses before doing the check.
