From 91d0be1dd845913ba276e041dc11d1297390de11 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 23 Jul 2014 06:54:58 -0600 Subject: [PATCH] stdio: Remove redundant code around stdio_register() calls There is no point in setting a structure's memory to NULL when it has already been zeroed with memset(). Also, there is no need to create a stub function for stdio to call - if the function is NULL it will not be called. This is a clean-up, with no change in functionality.
