io.h is for readl_relaxed() usage in this file. I added slab for the
devm_kcalloc() but it doesn't look necessary given that device.h is
where that is defined, not slab.h. Thanks for catching that!

Same here, io.h is for the readl_relaxed() and writel_relaxed() calls.
So please remove slab.h from the two files (but not the other one) when
applying. Thanks.
