pcmcia: pccard_read_tuple and TUPLE_RETURN_COMMON cleanup
pccard_read_tuple(), which is only used by the PCMCIA core, should
handle TUPLE_RETURN_COMMON more sensibly: If a specific function (which
may be 0) is requested, set tuple.Attributes = 0 as was done in all
PCMCIA drivers. If, however, BIND_FN_ALL is requested, return the
"common" tuple. As to the callers of pccard_read_tuple():
- All calls to pcmcia_validate_cis() had set the "function" parameter to
BIND_FN_ALL. Therefore, remove the "function" parameter and make the
parameter to pccard_read_tuple explicit.
- Calls to CISTPL_VERS_1 and CISTPL_MANFID now set BIND_FN_ALL. This was
already the case for calls to CISTPL_LONGLINK_MFC.
