[PATCH] Drivers: pci: code style cleanup
From: Chihau Chau
Date: Thu Mar 11 2010 - 12:53:19 EST
From: Chihau Chau <chihau@xxxxxxxxx>
This is a code style cleanup related with spaces, like a lot of trailing
withspaces, spaces before a TAB, to use "foo * bar" instead of "foo *bar"
and to put a else sentence below close brace '}'.
