The call to wakeup_source_register() in ipa_probe() does not do what it was intended to do. Call device_init_wakeup() in ipa_setup() instead, to set the IPA device as wakeup-capable and to initially enable wakeup capability. When we receive a SUSPEND interrupt, call pm_wakeup_dev_event() with a zero processing time, to simply call for a resume without any other processing. The ipa_resume() call will take care of waking things up again, and will handle receiving the packet. Note that this gets rid of a clock reference counting bug that occurred when handling an IPA SUSPEND interrupt. Specifically, ipa_suspend_handler() took an IPA clock reference *in addition* to the one taken by ipa_resume(). There is no need to back-port this fix however, because it only affects code that was not previously working (this patch is part of fixing that).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
