Subject: dm: core: Guard against including dm.h in header files
X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=a0558aca55c16a7f561656cb11bf172ef414bcec;p=u-boot.git

dm: core: Guard against including dm.h in header files

Header files generally should not include header files just for a struct,
since forward declarations work just as well and reduce overhead.

Add a warning for dm.h being included, since this has crept into U-Boot.
