From a4080f4f9d991baf832912192b40fc69dfa9783e Mon Sep 17 00:00:00 2001 From: William Douglas Date: Wed, 28 Sep 2011 10:50:39 +1000 Subject: [PATCH] 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.
