Code of Conflict
----------------
The Linux kernel development effort is a very personal process compared
to "traditional" ways of developing software. Your code and ideas
behind it will be carefully reviewed, often resulting in critique and
criticism. The review will almost always require improvements to the
code before it can be included in the kernel. Know that this happens
because everyone involved wants to see the best possible solution for
the overall success of Linux. This development process has been proven
to create the most robust operating system kernel ever, and we do not
want to do anything to cause the quality of submission and eventual
result to ever decrease.
If however, anyone feels personally abused, threatened, or otherwise
uncomfortable due to this process, that is not acceptable. If so,
please contact the Linux Foundation's Technical Advisory Board at
<tab@lists.linux-foundation.org>, or the individual members, and they
will work to resolve the issue to the best of their ability. For more
information on who is on the Technical Advisory Board and what their
role is, please see:
http://www.linuxfoundation.org/programs/advisory-councils/tab
As a reviewer of code, please strive to keep things civil and focused on
the technical issues involved. We are all humans, and frustrations can
be high on both sides of the process. Try to keep in mind the immortal
words of Bill and Ted, "Be excellent to each other."

interrupt source and an IRQF_NO_SUSPEND interrupt source does not generally
make sense.
In rare cases an IRQ can be shared between a wakeup device driver and an
IRQF_NO_SUSPEND user. In order for this to be safe, the wakeup device driver
must be able to discern spurious IRQs from genuine wakeup events (signalling
the latter to the core with pm_system_wakeup()), must use enable_irq_wake() to
ensure that the IRQ will function as a wakeup source, and must request the IRQ
with IRQF_COND_SUSPEND to tell the core that it meets these requirements. If
these requirements are not met, it is not valid to use IRQF_COND_SUSPEND.
