From c2a0b162dbce1534cf4e71914597419ae83a70d9 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Mon, 6 Dec 2010 10:02:11 +0300 Subject: [PATCH] Staging: Beceem: white space changes to InterfaceInit.c This patch only changes: 1) spaces, tabs, and newline characters. 2) comment styles. The compiled object file is the same before and after except for line number changes.
