spi: Convert uses of struct resource * to resource_size(ptr)
Joe Perches [Sat, 11 Jun 2011 01:11:25 +0000 (18:11 -0700)]
Done via coccinelle scripts like:

@@
struct resource *ptr;
@@

- ptr->end - ptr->start + 1
+ resource_size(ptr)

and some grep and typing.

Mostly uncompiled, no cross-compilers.
