Message-Id: <1396563423-30893-13-git-send-email-robherring2@gmail.com>
Date: Thu, 3 Apr 2014 17:16:55 -0500
From: Rob Herring <robherring2@...il.com>
To: linux-kernel@...r.kernel.org
Cc: Grant Likely <grant.likely@...aro.org>,
Rob Herring <robh@...nel.org>
Subject: [PATCH 12/20] of/fdt: update of_get_flat_dt_prop in prep for libfdt
From: Rob Herring <robh@...nel.org>
Make of_get_flat_dt_prop arguments compatible with libfdt fdt_getprop
call in preparation to convert FDT code to use libfdt. Make the return
value const and the property length ptr type an int.
Signed-off-by: Rob Herring <robh@...nel.org>
