Subject: [PATCH 1/3] driver core: Add ability for arch code to setup pdev_archdata
On some architectures we need to setup pdev_archdata before we add the
device. Waiting til a bus_notifier is too late since we might need the
pdev_archdata in the bus notifier. One example is setting up of dma_mask
pointers such that it can be used in a bus_notifier.
We add noop version of arch_setup_pdev_archdata() in
<asm-generic/platform_device.h> and allow the arch code to override with
access the full definitions of struct device, struct platform_device, and
struct pdev_archdata.
