From: Simon Glass Date: Sun, 2 Oct 2016 23:59:29 +0000 (-0600) Subject: libfdt: Sync fdt_for_each_subnode() with upstream X-Git-Tag: v2016.11-rc2~7^2~1 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=df87e6b1b815ae3484ea2aa7c53b90af382eae1b;p=u-boot libfdt: Sync fdt_for_each_subnode() with upstream The signature for this macro has changed. Bring in the upstream version and adjust U-Boot's usages to suit.
