To: torvalds, dahinds, davej, alan; +Cc: linux-kernel, pcmcia-cs-devel
A new device_class "pcmcia_socket_class" is introduced for PCMCIA and
CardBus sockets. All socket drivers I could find are updated so that they
register a driver, and -if necessary- the "platform"/legacy device. This
will allow for a cleanup of pcmcia_{un}register_socket() /
{un}register_ss_entry() as well as reflect the parent for pcmcia_bus
devices. Russell King allowed me to break sa1100_generic pcmcia support for
the time being - so drop that part of the patch for the moment.
