From 09c9feb94672bdb3ca6d424a292ffc26eff8ca0b Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 18 Nov 2010 12:27:32 -0800 Subject: Documentation: make configfs example code simpler, clearer If "p" is NULL then it will cause an oops when we pass it to simple_strtoul(). In this case "p" can not be NULL so I removed the check. I also changed the check a little to make it more explicit that we are testing whether p points to the NUL char.
