Message-ID: <12894188301399@xenotime.net> Date: Wed, 10 Nov 2010 11:53:50 -0800 From: Randy Dunlap <rdunlap@...otime.net> To: linux-kernel@...r.kernel.org Cc: Joel Becker <joel.becker@...cle.com> Subject: [PATCH 2/8] Documentation: make configfs example code simpler, clearer From: Dan Carpenter <error27@...il.com> 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.
