The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Instead of looking up a symbol name by hand, use the %ps printk format
specifier.

A platform_driver does not need to set an owner, it will be populated by the
driver core.

The Synology NAS devices use a very similar mechanism to QNAP NAS
devices to power off. Both send a single charactor command to a PIC,
over the second serial port. However the baud rate and the command
differ. Generalize the driver to support this.

The QNAP NAS boxes have a microcontroller attached to the SoCs second
serial port. By sending it a simple command, it will turn the power for
the board off. This driver registers a function for pm_power_off to send
such a command.
