ChangeSet@1.728, 2002-10-09 10:52:46-07:00, mochel@osdl.org
IDE: register ide driver for all ide drives; not just for disk drives.
This adds
struct device_driver gen_driver;
to ide_driver_t, which is filled in with necessary fields when an ide
driver calls ide_register_driver(). That then registers the driver with
the driver model core.
As a result, this gives us the following output in driverfs:
# tree -d /sys/bus/ide/drivers/
/sys/bus/ide/drivers/
|-- ide-cdrom
`-- ide-disk
The suspend/resume callbacks in ide-disk.c have been temporarily
disabled until the ide core implements generic methods which forward
the calls to the drive drivers.
