Using devres + kalloc to allocate 1-4 pointers feels a bit strange. Quick grep shows over 150 instances that could be updated to use the new API. Adding a cocci script to simplify the transition would be a good idea. > --- a/include/linux/clk.h > +++ b/include/linux/clk.h > @@ -15,6 +15,7 @@ > #include <linux/err.h> > #include <linux/kernel.h> > #include <linux/notifier.h> > +#include <linux/slab.h> > The extra header declaration should not be needed. One should be able to forward declare any undefined structs.
