That is not really true. A driver does have intimate knowledge of the
device, however it does not necessarily have an idea about the data read
from the device. Consider the gpio_matrix driver: Arve says that it has
to continue scanning matrix once first interrupt arrvies. But it really
depends on what key has been pressed - if user pressed KEY_SUSPEND or
KEY_POWER it cmight be better if we did not wait for key release but
initiated the action right away. The decision on how system reacts to a
key press does not belong to the driver but really to userspace.
