[PATCH 2/2] DSPBRIDGE: Various compile warning fixes

Felipe Contreras
2010-01-23T10:20:10Z

From: Mika Kukkonen <mika.kukkonen@nokia.com>

This patch contains indentation fixes and cleans up various warnings
uncovered with extra warning flags:
- empty if() bodies
- incorrect use of unsigned variables
- bad comparison of pointer value
- pointless check of unsigned value being smaller than zero
- keyword 'extern' has to be first one in variable declaration
