Summary
mtd: rawnand: cadence: fix possible null-ptr-deref in cadence_nand_dt_probe()
Details

In the Linux kernel, the following vulnerability has been resolved:

mtd: rawnand: cadence: fix possible null-ptr-deref in cadencenanddt_probe()

It will cause null-ptr-deref when using 'res', if platformgetresource() returns NULL, so move using 'res' after devmioremapresource() that will check it to avoid null-ptr-deref. And use devmplatformgetandioremap_resource() to simplify code.
