We do have a TST_RETRY_FUNC() in include/tst_common.h that is slightly
smarter than this loop and also properly scales the timeout on slow
devices automaticaly. So this should be:

	if (!TST_RETRY_FUNC(access(path, F_OK), TST_RETVAL_NULL)) {
		tst_res(TINFO, "Found event device: %s", path);
		break;
	}
