[PATCH] EFIFB: Fix error handling

From: David Howells
Date: Tue Jun 14 2011 - 20:39:41 EST


Fix the error handling in the EFIFB driver if platform_driver_probe() fails.
In that case, the code will pass the driver struct to the _device_
unregistration function. It presumably should pass a pointer to the device
struct instead.

The compiler gives the following warning to indicate this:

drivers/video/efifb.c: In function 'efifb_init':
drivers/video/efifb.c:544:3: warning: passing argument 1 of 'platform_device_unregister' from incompatible pointer type
include/linux/platform_device.h:40:13: note: expected 'struct platform_device *' but argument is of type 'struct platform_driver *'
