The current design of callback function disable() of struct nvkm_devinit_func is defined to return a u64 value. In its implementation in the driver modules, the function always returns a fixed value 0. Hence the design and implementation of this function should be enhanced to return void instead of a fixed value. This change also eliminates untouched return variables. The change is identified using the returnvar.cocci Coccinelle semantic patch script.
