Subject: dt: Add empty of_match_node() macro
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5762c20593b6b959f1470dc6f1ff4ca4d9570f8d;p=linux-beck.git

dt: Add empty of_match_node() macro

Add an empty macro for of_match_node() that will save
some '#ifdef CONFIG_OF' for non-dt builds.

I have chosen to use a macro instead of a function to
be able to avoid defining the first parameter.
In fact, this "struct of_device_id *" first parameter
is usualy not defined as well on non-dt builds.
