It added a pr_debug() message which is issued when deadline timer validation succeeds. Well, issued only when CONFIG_DYNAMIC_DEBUG is enabled - otherwise pr_debug() calls get optimized away if DEBUG is not defined in the compilation unit. Therefore, make the above message pr_info() so that it is visible in dmesg.
