From d50dbec3ce52e1608636b8a624d087da9ced8cde Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Fri, 23 Oct 2009 12:51:28 +0200 Subject: pcmcia: use dynamic debug instead of custom infrastructure Use the generic "dynamic debug" infrastructure instead of CONIG_PCMCIA_DEBUG in the PCMCIA core (pcmcia.ko and pcmcia_core.ko). To enable debugging, enable CONFIG_DYNAMIC_DEBUG, mount debugfs and $ echo -n 'module pcmcia_core +p' > /sys/kernel/debug/dynamic_debug/control for the complete module "pcmcia_core", for example.
