[PATCH] dma-mapping.c: local variables should not be exposed globaly

[H Hartley Sweeten]

The variable 'consistent_base' is only referenced in this file and
should be marked static to prevent it from being exposed globably.

This quiets the sparse warning:

warning: symbol 'consistent_base' was not declared. Should it be static?
