This allows us to eliminate the casts in the drivers, and eventually remove the use of the device_driver function pointer methods for platform device drivers. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Acked-by: Greg Kroah-Hartman <gregkh@suse.de>

* macsonic.c
|
|
*
|
|
* (C) 2005 Finn Thain
|
|
*
|
|
* Converted to DMA API, converted to unified driver model, made it work as
|
|
* a module again, and from the mac68k project, introduced more 32-bit cards
|
|
* and dhd's support for 16-bit cards.
|
|
*
|
|
* (C) 1998 Alan Cox
|
|
*
|
|
* Debugging Andreas Ehliar, Michael Schmitz
|
|
*
|
|
* Based on code
|
|
* (C) 1996 by Thomas Bogendoerfer (tsbogend@bigbug.franken.de)
|
|
*
|
|
* This driver is based on work from Andreas Busse, but most of
|
|
* the code is rewritten.
|
|
*
|
|
* (C) 1995 by Andreas Busse (andy@waldorf-gmbh.de)
|
|
*
|
|
* A driver for the Mac onboard Sonic ethernet chip.
|
|
*
|
|
* 98/12/21 MSch: judged from tests on Q800, it's basically working,
|
|
* but eating up both receive and transmit resources
|
|
* and duplicating packets. Needs more testing.
|
|
*
|
|
* 99/01/03 MSch: upgraded to version 0.92 of the core driver, fixed.
|
|
*
|
|
* 00/10/31 sammy@oh.verio.com: Updated driver for 2.4 kernels, fixed problems
|
|
* on centris.
