Revision 9468613b2bb0a386af563953b613efc6c77bd8c1 authored by Russell King on 28 October 2006, 21:42:56 UTC, committed by Russell King on 28 October 2006, 21:42:56 UTC
The PXA2xx PCMCIA driver was registering a device_driver with the platform_bus_type. Unfortunately, this causes data outside the device_driver structure to be dereferenced as if it were a platform_driver structure, causing an oops. Convert the PXA2xx core driver to use the proper platform_driver structure. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
