Subject: [PATCH] selftests: vDSO: parse: warning: fix assignment as a condition
Date: Fri, 5 Nov 2021 17:27:56 +0100 [thread overview]
Message-ID: <20211105162756.3314148-1-anders.roxell@linaro.org> (raw)
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.
