Subject: of/flattree: forward declare struct device_node in of_fdt.h
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a081748735c5feb96b1365e78a5ff0fb6ca7e3a4;p=linux-beck.git

of/flattree: forward declare struct device_node in of_fdt.h

This patch forward declares struct device_node to fix a compile error
when of_fdt.h is included, but of.h is not.  Alternately, including
linux/of.h could have been added to of_fdt.h, but that pulls in a lot
of unnecessary declarations when only working with the flattened
form.
