Summary
mtd: rawnand: intel: fix possible null-ptr-deref in ebu_nand_probe()
Details

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

mtd: rawnand: intel: fix possible null-ptr-deref in ebunandprobe()

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.
