SubjectRe: [PATCH] pcmcia: get initialization ordering right [Was: [PATCH 2.5] : i82365 & platform_bus_type]
Hi Pat,

How is it supposed to work then? I thought adding a platform_device and
platform_driver with the same name and bus_id causes the platform_driver to
be bound to the platform_device?

Thanks,
Dominik
