This reverts commit e6c7efdcb76f11b04e3d3f71c8d764ab75c9423b. Turns out it was totally wrong. The memory is supposed to be bound to the kref, as the original code was doing correctly, not the device/driver binding as the devm_kzalloc() would cause. This fixes an oops when read would be called after the device was unbound from the driver.
