From 906a9dbbcba85e8b02414c960c75103cc4755102 Mon Sep 17 00:00:00 2001 From: Jean-Jacques Hiblot Date: Fri, 15 Sep 2017 12:57:25 +0200 Subject: [PATCH] fit: use 'const' for the input of fdt_offset() and locate_dtb_in_fit() Those 2 functions don't modify their input, we can mark it const. This prevents compilation warnings when they are provided const input.
