Date: Mon, 15 Aug 2011 14:54:04 -0700 From: William Douglas <william.r.douglas@...il.com> To: linux-kernel@...r.kernel.org Subject: [PATCHv2] printk: Remove bounds checking for log_prefix Currently log_prefix is testing that the first character of the log level and facility is less than '0' and greater than '9' (which is always false). Since the code being updated works because strtoul bombs out (endp isn't updated) and 0 is returned anyway just remove the check and don't change the behavior of the function.
