Subject: [PATCH] kunit: Fix NULL-dereference in kunit_init_suite() if suite->log is NULL
Date: Mon, 18 Dec 2023 15:17:29 +0000 [thread overview]
Message-ID: <20231218151729.210027-1-rf@opensource.cirrus.com> (raw)
suite->log must be checked for NULL before passing it to
string_stream_clear(). This was done in kunit_init_test() but was missing
from kunit_init_suite().
Signed-off-by: Richard Fitzgerald <rf@opensource.cirrus.com>
Fixes: 6d696c4695c5 ("kunit: add ability to run tests after boot using debugfs")
