[PATCH 3/3] firewire: fw-ohci: shut up false compiler warning onPPC32

From: Stefan Richter
Date: Fri Feb 29 2008 - 20:51:11 EST


Shut up two "may be used uninitialised in this function" warnings due to
PPC32's implementation of dma_alloc_coherent().

Signed-off-by: Stefan Richter <stefanr@xxxxxxxxxxxxxxxxx>

Wasn't there a macro somewhere for this?

Also, could this be better done in PPC32's dma_alloc_coherent()?
At least this kind of workaround here doesn't add anything to the
compiled result.
