the local variable ops and n_ops were just read out from family,
and not changed, hence no need to assign back.
Validation functions should operate on const parameters and not
change anything.

The site-specific OOM messages are unnecessary, because they
duplicate the MM subsystem generic OOM message. For example,
k.alloc and v.alloc failures use dump_stack().

Intel Haswell has the same I2C host controller than Baytrail and it can
also be enumerated as a PCI device. Add the PCI IDs to the driver list.

It is possible that after entering runtime PM suspend the controller
context is lost due the fact that its power is removed. This happens for
example on Asus T100, an Intel Baytrail based tablet/laptop.
In order to get the controller back to functional state, we need to
implement runtime PM hooks which will re-initialize the hardware during
runtime PM resume. We can re-use the existing system suspend hooks as the
steps to resume/suspend the controller are the same.

Userspace can initiate system suspend on arbitrary times which means that
device drivers must make sure that their device gets quiesced before system
suspend is entered. Therefore disable the I2C host controller in the driver
system suspend hook.

Arnd said in another patch:
"As far as I can tell, this driver must have produced this
error for as long as it has been merged into the mainline kernel, but
it was never part of the normal build tests:
drivers/i2c/busses/i2c-nuc900.c: In function 'nuc900_i2c_probe':
drivers/i2c/busses/i2c-nuc900.c:601:17: error: request for member
'apbfreq' in something not a structure or union
ret = (i2c->clk.apbfreq)/(pdata->bus_freq * 5) - 1;
^
This is an attempt to get the driver to build and possibly
work correctly, although I do wonder whether we should just
remove it, as it has clearly never worked."
I agree with removing it since nobody showed interest in Arnd's fixup
patch.

Since IMX serial SOCs support low bus freq mode, some clocks freq
may change to save power. I2C needs to check the clock source and
update the divider.
For example:
i.MX6SL I2C clk is from IPG_PERCLK which is sourced from IPG_CLK.
Under normal operation, IPG_CLK is 66MHz, ipg_perclk is at 22MHz.
In low bus freq mode, IPG_CLK is at 12MHz and IPG_PERCLK is down
to 4MHz. So the I2C driver must update the divider register for
each transaction when the current IPG_PERCLK is not equal to the
clock of previous transaction.

Test i2c device Maxim max44009, datasheet is located at:
http://www.maximintegrated.com/datasheet/index.mvp/id/7175
The max44009 support repeat operation like:
read -> repeat restart -> read/write
The current i2c imx host controller driver don't support this
operation that causes i2c bus hang due to "MTX" is cleared in
.i2c_imx_read(). If "read" is the last message there have no problem,
so the current driver supports all SMbus operation like:
write -> repeat restart -> read/write
IMX i2c controller for master receiver has some limitation:
- If it is the last byte for one operation, it must generate STOP
signal before read I2DR to prevent controller from generating another
clock cycle.
- If it is the last byte in the read, and then do repeat restart, it must
set "MTX" before read I2DR to prevent controller from generating another
extra clock cycle.
The patch is to fix the issue.

Pull block core updates from Jens Axboe:
"It's a big(ish) round this time, lots of development effort has gone
into blk-mq in the last 3 months. Generally we're heading to where
3.16 will be a feature complete and performant blk-mq. scsi-mq is
progressing nicely and will hopefully be in 3.17. A nvme port is in
progress, and the Micron pci-e flash driver, mtip32xx, is converted
and will be sent in with the driver pull request for 3.16.
This pull request contains:
- Lots of prep and support patches for scsi-mq have been integrated.
All from Christoph.
- API and code cleanups for blk-mq from Christoph.
- Lots of good corner case and error handling cleanup fixes for
blk-mq from Ming Lei.
- A flew of blk-mq updates from me:
* Provide strict mappings so that the driver can rely on the CPU
to queue mapping. This enables optimizations in the driver.
* Provided a bitmap tagging instead of percpu_ida, which never
really worked well for blk-mq. percpu_ida relies on the fact
that we have a lot more tags available than we really need, it
fails miserably for cases where we exhaust (or are close to
exhausting) the tag space.
* Provide sane support for shared tag maps, as utilized by scsi-mq
* Various fixes for IO timeouts.
* API cleanups, and lots of perf tweaks and optimizations.
- Remove 'buffer' from struct request. This is ancient code, from
when requests were always virtually mapped. Kill it, to reclaim
some space in struct request. From me.
- Remove 'magic' from blk_plug. Since we store these on the stack
and since we've never caught any actual bugs with this, lets just
get rid of it. From me.
- Only call part_in_flight() once for IO completion, as includes two
atomic reads. Hopefully we'll get a better implementation soon, as
the part IO stats are now one of the more expensive parts of doing
IO on blk-mq. From me.
- File migration of block code from {mm,fs}/ to block/. This
includes bio.c, bio-integrity.c, bounce.c, and ioprio.c. From me,
from a discussion on lkml.
That should describe the meat of the pull request. Also has various
little fixes and cleanups from Dave Jones, Shaohua Li, Duan Jiong,
Fengguang Wu, Fabian Frederick, Randy Dunlap, Robert Elliott, and Sam
Bradshaw"

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v3.16 series.
There is a lot of action in the GPIO subsystem doing refactorings and
cleanups, almost as many deletions as insertions and minor feature
growth and no new drivers this time. Which is actually pretty nice.
Some GPIO-related stuff will come in through the pin control tree as
well.
Details:
- We are finalizing and fixing up the gpiochip irqchip helpers
bringing a helpful irqchip implementation into the gpiolib core and
avoiding duplicate code and, more importantly, duplicate bug fixes:
* Support for using the helpers with threaded interrupt handlers as
used on sleeping GPIO-irqchips
* Do not set up hardware triggers for edges or levels if the
default IRQ type is IRQ_TYPE_NONE - some drivers would exploit
the fact that you could get default initialization of the IRQ
type from the core at probe() but if no default type is set up
from the helper, we should not call the driver to configure
anything. Wait until a consumer requests the interrupt instead.
* Make the irqchip helpers put the GPIO irqs into their own lock
class. The GPIO irqchips can often emit (harmless, but annoying)
lockdep warnings about recursions when they are in fact just
cascaded IRQs. By putting them into their own lock class we help
the lockdep core to keep track of things.
* Switch the tc3589x GPIO expanders to use the irqchip helpers
* Switch the OMAP GPIO driver to use the irqchip helpers
* Add some documentation for the irqchip helpers
* select IRQ_DOMAIN when using the helpers since some platforms may
not be using this by default and it's a strict dependency.
- Continued GPIO descriptor refactoring:
* Remove the one instance of gpio_to_desc() from the device tree
code, making the OF GPIO code use GPIO descriptors only.
* Introduce gpiod_get_optional() and gpiod_get_optional_index()
akin to the similar regulator functions for cases where the use
of GPIO is optional and not strictly required.
* Make of_get_named_gpiod_flags() private - we do not want to
unnecessarily expose APIs to drivers that make the gpiolib harder
than necessary to maintain and refactor. Privatize this
function.
- Support "-gpio" suffix for the OF GPIO retrieveal path. We used to
look for "foo-gpios" or just "gpios" in device tree nodes, but it
turns out that some drivers with a single GPIO line will just state
"foo-gpio" (singularis). Sigh. Support this with a fallback
looking for it, as this simplifies driver code and handles it in
core code.
- Switch the ACPI GPIO core to fetch GPIOs with the *_cansleep
function variants as the GPIO operation region handler can sleep,
and shall be able to handle gpiochips that sleep.
- Tons of cleanups and janitorial work from Jingoo Han, Axel Lin,
Javier Martinez Canillas and Abdoulaye Berthe. Notably Jingoo cut
off a ton of pointless OOM messages.
- Incremental development and fixes for various drivers, nothing
really special here"
