Subject: [ 10/82] mISDN: Bugfix only few bytes are transfered on a connection

From: Greg KH <gregkh@...uxfoundation.org>

3.5-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Karsten Keil <keil@...systems.de>

commit b41a9a66f67817f8acd85bd650e012a14da39faa upstream.

The test for the fillempty condition was wrong in one place.
Changed the variable to the right boolean type.
