[PATCH AUTOSEL 5.4 078/187] kselftest/runner: Print new line in print of timeout log

by Sasha Levin

From: SeongJae Park <sjpark(a)amazon.de> [ Upstream commit d187801d1a46519d2a322f879f7c8f85c685372e ] If a timeout failure occurs, kselftest kills the test process and prints the timeout log. If the test process has killed while printing a log that ends with new line, the timeout log can be printed in middle of the test process output so that it can be seems like a comment, as below: # test_process_log not ok 3 selftests: timers: nsleep-lat # TIMEOUT This commit avoids such problem by printing one more line before the TIMEOUT failure log.
