Subject: [PATCH] PNP: make resource assignment functions return 0 (success) or
 -EBUSY (failure)

This patch doesn't change any behavior; it just makes the return
values more conventional.

This changes pnp_assign_dma() from a void function to one that
returns an int, just like the other assignment functions.  For
now, at least, pnp_assign_dma() always returns 0 (success), so
it appears to never fail, just like before.
