[PATCH 11/16] pcmcia: use dynamic debug infrastructure, deprecate CS_CHECK (scsi)
Dominik Brodowski
linux at dominikbrodowski.net
Sat Oct 24 15:43:01 EDT 2009
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.
