ChangeSet@1.696.19.2, 2002-10-07 10:27:16-07:00, 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.
