using UBI and DM together leads in compiler error, as both define a "struct device", so rename "struct device" in include/dm/device.h to "struct udevice", as we use linux code (MTD/UBI/UBIFS some USB code,...) and cannot change the linux "struct device" Signed-off-by: Heiko Schocher <hs@denx.de> Cc: Simon Glass <sjg@chromium.org> Cc: Marek Vasut <marex@denx.de>
