From e773cfe167c320d07b9423bc51fc4ab0221775a4 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Sat, 24 Oct 2009 15:50:13 +0200 Subject: pcmcia: use dynamic debug infrastructure, deprecate CS_CHECK (isdn) Convert PCMCIA drivers to use the dynamic debug infrastructure, instead of requiring manual settings of PCMCIA_DEBUG. Also, remove all usages of the CS_CHECK macro and replace them with proper Linux style calling and return value checking. The extra error reporting may be dropped, as the PCMCIA core already complains about any (non-driver-author) errors.
