[PATCH 02/18] dmaengine/amba-pl08x: Resolve formatting issues

Fri Jul 29 06:49:12 EDT 2011
There were few formatting related issues in code. This patch fixes them.
Fixes include:
- Remove extra blank lines and spaces
- align code to 80 cols
- Don't mix spaces and tabs (use tabs instead)
- combine several lines to one line
