When this functionality was first implemented, visorchipset and visorbus were separate drivers, which necessitated a registration mechanism for them to communicate. More-recently, visorchipset and visorbus were combined into a single driver, and now exist as separate source files within the same driver, known as 'visorbus'. This eliminated the need for a registration mechanism, but it has remained nevertheless until now. For the sake of simplification, this registration mechanism is now being removed.

A kernel timer is now used as the vehicle to periodically call the channel_interrupt function of registered visor drivers, instead of a workqueue. This simplifies a lot of things by making periodic_work.c and periodic_work.h no longer necessary. This change also means that the channel_interrupt() callbacks registered by visor drivers (via visorbus_register_visor_driver()) will now be called in atomic context (i.e., canNOT sleep) rather than kernel thread context (CAN sleep). Fortunately this did NOT necessitate any change to the existing channel_interrupt() callbacks, because none of them ever perform any operations that would be invalid in atomic context.

Locking in the _interrupt() function is NOT necessary so long as we ensure that interrupts have been stopped whenever we need to pause or resume the device, which we now do. While a device is paused, we ensure that interrupts stay disabled, i.e. that the _interrupt() function will NOT be called, yet remember the desired state in devdata->interrupts_enabled if open() or close() are called are called while the device is paused. Then when the device is resumed, we restore the actual state of interrupts (i.e., whether _interrupt() is going to be called or not) to the desired state in devdata->interrupts_enabled.
