[PATCH 14/16] pcmcia: use dynamic debug infrastructure, deprecate CS_CHECK (misc drivers)

Dominik Brodowski
2009-10-24T19:43:29Z

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.
