From 11e44fc6bda2248271d26a8488f5efe189b55a30 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Fri, 5 Aug 2016 09:47:50 -0600 Subject: fdt_support: fdt_translate_address() blob const correctness The next patch will call fdt_translate_address() from somewhere with a "const void *blob" rather than a "void *blob", so fdt_translate_address() must accept a const pointer too. Constify the minimum number of function parameters to achieve this.
