Subject: [PATCH] Staging: hv: Transform PDEVICE_OBJECT and DEVICE_OBJECT typedefs into their corresponding structs


Remove typedef DEVICE_OBJECT and use a struct with the same name
instead. The new struct name uses lower case (struct device_object).

Remove typedef PDEVICE_OBJECT which aliases a pointer and use the
corresponding renamed struct pointer (struct device_object *).

Here is the semantic patch generated to perform this transformation:
(http://www.emn.fr/x-info/coccinelle/)
