Most interrupt flow handlers do not use the irq argument. Those few
which use it can retrieve the irq number from the irq descriptor.

Remove the argument.

Search and replace was done with coccinelle and some extra helper
scripts around it. Thanks to Julia for her help!

Use irq_desc_get_xxx() to avoid redundant lookup of irq_desc while we
already have a pointer to corresponding irq_desc.

Do the same change to avoid the pattern "irq_get_chip_data(data-&gt;irq)".

Chained irq handlers usually set up handler data as well. We now have
a function to set both under irq_desc-&gt;lock. Replace the two calls
with one.

Search and conversion was done with coccinelle.

<title>mfd: Kill off set_irq_flags usage</title>

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:

IRQF_VALID -&gt; !IRQ_NOREQUEST
IRQF_PROBE -&gt; !IRQ_NOPROBE
IRQF_NOAUTOEN -&gt; IRQ_NOAUTOEN

For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also modify IRQ_NOPROBE and this has been maintained although it
is not clear that is really needed. There appears to be a great deal of
blind copy and paste of this code.

  They are dominated by the removal of the .owner field in platform

  just removing a line in a structure.

  Other than that, a few minor driver core and debugfs changes.  There
  are some ath9k patches coming in through this tree that have been
  acked by the wireless maintainers as they relied on the debugfs
  changes.

  Everything has been in linux-next for a while"

<content type='text'>
Some boards with TC6393XB chip require full state restore during system
resume thanks to chip's VCC being cut off during suspend (Sharp SL-6000
tosa is one of them). Failing to do so would result in ohci Oops on
resume due to internal memory contentes being changed. Fail ohci suspend
on tc6393xb is full state restore is required.

Recommended workaround is to unbind tmio-ohci driver before suspend and
rebind it after resume.
