From bc6ed0f9dc56fe1738646e6882a0b87e6766eaaa Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 18 Apr 2014 17:41:00 +0900 Subject: [PATCH] fdt_support: delete force argument of fdt_chosen() After all, we have realized "force" argument is completely useless. fdt_chosen() was always called with force = 1. We should always want to do the same thing (set appropriate value to the property) even if the property already exists.
