Linus Torvalds dfc1ebe766 Device tree conversions for samsung and tegra
Both platforms had some initial device tree support, but this adds
 much more to actually make it usable.
 
 This is where the really nasty conflicts in the samsung platform
 start, due to some files getting moved around and combined in the
 'restart' branch that has already gone into mainline through
 Russell's tree.

The sysdev.h file should not be needed by any in-kernel code, so remove

The sysdev code will be going away soon, so this include needs to be
