From bda32ffcf712806c7880ded25a012fbeede35e80 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 24 Feb 2013 17:33:12 +0000 Subject: [PATCH] Update print_buffer() to use const The buffer cannot be changed by this function, so change the buffer pointer to a const. This allows callers with const pointer to use the function without a cast.
