Subject: [BUG REPORT!!!] [PATCH 19/49] pcmcia: remove remaining in-kernel
 pcmcia_get_configuration_info() users

Dear Dominik

Unfortunately, your path "[PATCH 19/49] pcmcia: remove remaining in-kernel
pcmcia_get_configuration_info() users"
broke the "serial_cs" and other drivers.

You replace "config->BasePort2" to "link->io.BasePort2" at serial_cs. 

But link->io.BasePort2, link->io.NumPorts2(etc) 
does not contain correct value (it is zero).

Please fix this problem (or reveart the patch).


Best Regards
Komuro

Here is your patch.
