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. Signed-off-by: Joe Perches <joe@perches.com>
