[PATCH 2/3] Some patches for 2.6.15

The attached patch is my attempt to cope with an extra parameter added 
to the class_device_create function in kernel 2.6.15.  There is more 
than one way to work around this in the compatibility headers, but they 
all have a certain amount of ugliness due to the function taking a 
variable number of parameters.

My patch requires code to call CLASS_DEVICE_CREATE instead of 
class_device_create, but it's only called from one place, so it's not so 
bad.
