Allocate memory for device state using devm_kzalloc() to simplify accounting and letting the kernel do the garbage-collection.
Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> --- Changes V1 -> V2: No change, generated new patch for V2 series.
Changes V2->V3: Revert the request registration through devm_* and use the normal api.
