5. Runtime PM Initialization, Device Probing and Removal
Initially, the runtime PM is disabled for all devices, which means that the

-EAGAIN until pm_runtime_enable() is called for the device.
In addition to that, the initial runtime PM status of all devices is
in a special way. Namely, the IRQ remains enabled, by on the first interrupt
it will be disabled, marked as pending and "suspended" so that it will be
re-enabled by resume_device_irqs() during the subsequent system resume. Also
-the PM core is notified about the event which casues the system suspend in
+the PM core is notified about the event which causes the system suspend in
progress to be aborted (that doesn't have to happen immediately, but at one
of the points where the suspend thread looks for pending wakeup events).
The device's read() operation can be used to transfer the snapshot image from
the kernel. It has the following limitations:
- you cannot read() more than one virtual memory page at a time
-- read()s across page boundaries are impossible (ie. if ypu read() 1/2 of
+- read()s across page boundaries are impossible (ie. if you read() 1/2 of
a page in the previous call, you will only be able to read()
_at_ _most_ 1/2 of the page in the next call)
