From 475be4d85a274d0961593db41cf85689db1d583c Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Sun, 19 Feb 2012 19:52:38 -0800 Subject: isdn: whitespace coding style cleanup isdn source code uses a not-current coding style. Update the coding style used on a per-line basis so that git diff -w shows only elided blank lines at EOF. Done with emacs and some scripts and some typing. Built x86 allyesconfig. No detected change in objdump -d or size.
