Fix mismerge due to devnode now taking a 'const *' device

This was a mismerge of a semantic conflict in my merge of the driver
core updates, where commit ff62b8e6 ("driver core: make struct
class.devnode() take a const *") changed the devnode function pointer
type.  In the meantime, the drm tree I merged earlier had introduced a
new use of that in commit 8bf48897 ("drivers/accel: define kconfig
and register a new major").

And of course this happens when I'm traveling with my laptop, and thus
didn't do a full allmodconfig build between every pull and before
pushing my work out.

So I only noticed later as I was doing my full build.
