* Make ide_unregister() take 'ide_hwif_t *hwif' instead of 'unsigned int index' (hwif->index) as an argument and update all users accordingly. While at it: * Remove unnecessary checks for hwif != NULL from ide-pnp.c::idepnp_remove() and delkin_cb.c::delkin_cb_remove(). * Remove needless hwif->chipset assignment from scc_pata.c::scc_remove(). v2: * Fixup ide_unregister() documentation.

* Created 20 Oct 2004 by Mark Lord
|
|
*
|
|
* Basic support for Delkin/ASKA/Workbit Cardbus CompactFlash adapter
|
|
*
|
|
* Modeled after the 16-bit PCMCIA driver: ide-cs.c
|
|
*
|
|
* This is slightly peculiar, in that it is a PCI driver,
|
|
* but is NOT an IDE PCI driver -- the IDE layer does not directly
|
|
* support hot insertion/removal of PCI interfaces, so this driver
|
|
* is unable to use the IDE PCI interfaces. Instead, it uses the
|
|
* same interfaces as the ide-cs (PCMCIA) driver uses.
|
|
* On the plus side, the driver is also smaller/simpler this way.
|
