From d975ce21ce92b2b0c6d13b0a8b5b4d78bfd37113 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 27 Jan 2020 08:49:39 -0700 Subject: [PATCH] dm: core: Use const device for the devfdt...() interface These functions do not modify the device so should use a const pointer to it. Update the code accordingly.
