Thanks for diagnosing the problem but it doesn't make any sense at all.
 Those three lines just clear cached SError value.  pata_pcmcia being a
PATA driver, SError is not implemented and always zero.

Also the init_one error is -ENOMEM.  For the above change to make any
difference, EH should have been entered which is invoked deep into
ata_host_register() and once control reaches that point it never returns
error code.  I have difficult time imagining any way the above diff can
have anything to do with the reported failure.

Please apply the attached patch and report the log after probe failure.
