types.h defines device_t as a typedef of struct device *. struct device is defined in subr_bus.c and almost all of the kernel uses device_t. The LinuxKPI also defines a struct device, so type confusion can occur. This causes bugs and ambiguity for debugging tools. Rename the FreeBSD struct device to struct _device.
