No, of course not. This patch is just a first step to get hx4700 suspend
mode working; currently it does not work at all.

The suspend mode disposition of devices and GPIOs still needs to be
reviewed at some point. For example, someone else discovered that the two
Bluetooth outputs (GPIO43, GPIO45) account for approximately one third of
the suspend mode power consumption! Correcting that will be my next patch.

Regards,
Paul
