[PATCH] selftests: vDSO: parse: warning: fix assignment as a condition

From: Anders Roxell
Date: Fri Nov 05 2021 - 12:28:11 EST


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 /home/anders/.cache/tuxmake/builds/current/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.
