From 4306cad6fe02e2946183ab29e510f94190b8fff3 Mon Sep 17 00:00:00 2001 From: Simon Farnsworth Date: Mon, 19 Jan 2009 21:19:29 +0000 Subject: solos: Slight debugging improvements Print a message if pskb_expand_head fails. Make atmdebug writable by root, so that you can turn printing of data sent to and received from the card on and off at runtime - useful for tracking corruption.
