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>

* How to use:
|
|
*
|
|
* Before including this file, you need to
|
|
* #define __debug_variable my_debug
|
|
* where my_debug is a variable in your code which
|
|
* determines the debug bitmask.
|
|
*
|
|
* If CONFIG_HISAX_DEBUG is not set, all macros evaluate to nothing
