From ae29bc92da01a2e9d278a9a58c3b307d41cc0254 Mon Sep 17 00:00:00 2001 From: William Douglas Date: Mon, 31 Oct 2011 17:11:31 -0700 Subject: 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.
