using headers for platform device outside of the staging tree

[Marc Dietrich]

Hi Greg,

i like to use the nvec driver with an arm soc board. What's the "usual" way to get 
access to the platform data (in nvec.h)? I see three options:

	a) just add #include "../../../drivers/staging/nvec/nvec.h" to the board file as 
long as the driver is still in staging and update it after the driver got blessed

	b) create some standalone file in include/linux/platform_data/tegra_nvec.h with 
just the platform data inside

	c) don't try to include a staging driver in a mainline file (well, that's the 
worst option)

Any hints?

Thanks

Marc
