First round of IIO fixes for the 3.10 cycle.

The usual mixed bag of little fixes.

1) A fix for mxs-lradc having missed out on some global abi changes that and
   hence being unable to start up buffered output.
2) Clean up error handling in tsl2x7x
3) A build fix for some of the dac drivers when they have spi master support
   built in, but i2c support build as a module.
4) Add a missing disable after a oneshot capture to the st sensor core.
5) Exynos adc driver took a novel an incorrect route to get at its private
   data store.

The exynos_adc device structure was wrongly extracted from the dev*
correcting the same.

Using the regular conversion of
struct device* -> struct platform_device* -> struct exynos_adc* seems wrong.
Instead we should be doing
struct device* -> struct iio_dev* -> struct exynos_adc*

This patch fixes below build error when CONFIG_SPI_MASTER=y && CONFIG_I2C=m:

make: *** [vmlinux] Error 1

When CONFIG_I2C=m, meaning we can't build the drivers in with I2C support.
Thus don't allow the drivers to be compiled as built-in when CONFIG_I2C=m.

The real fix though is to break the driver apart into a SPI part, an I2C part
and a common part. But that's something for 3.11 while this is something for
3.10/stable.

virt_to_page() is typically implemented as a macro containing a cast so
that it will accept both pointers and unsigned long without causing a
warning.

But MIPS virt_to_page() uses virt_to_phys which is a function so passing
an unsigned long will cause a warning:

    CC      mm/page_alloc.o
  mm/page_alloc.c: In function ‘free_reserved_area’:

local_irq_enable() may expand into very different code, so it rather should
stay in C.  Also this keeps the assembler code size constant which keeps
the rollback code simple.  So it's best to split r4k_wait into two parts,
one C and one assembler.

Finally add the local_irq_enable() to r4k_wait to ensure the WAIT
instruction in __r4k_wait() will work properly.

Pull LED subsystem fix from Bryan Wu.

* 'leds-fixes-3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/linux-leds:
  leds: leds-gpio: reserve gpio before using it

This reverts commit a99d76f9 (leds: leds-gpio: use gpio_request_one)
and commit 2d7c22f6 (leds: leds-gpio: set devm_gpio_request_one()
flags param correctly) which was a fix of the first one.

The conversion to devm_gpio_request in commit e3b1d44c (leds:
leds-gpio: use devm_gpio_request_one) is not reverted.

The problem is that gpio_cansleep() and gpio_get_value_cansleep()
calls can crash if the gpio is not first reserved. Incidentally this
same bug existed earlier and was fixed similarly in commit d95cbe61
(leds: Fix potential leds-gpio oops). But the OOPS is real. It happens
when GPIOs are provided by module which is not yet loaded.

So this fixes the following BUG during my ALIX boot (3.9.2-vanilla):

Pull i2c bugfixes from Wolfram Sang:
 "These should have been in rc2 but I missed it due to working on devm
  longer than expected.

  There is one ID addition, since we are touching the driver anyhow.
  And the feature bit documentation is one outcome of a debug session
  and will make it easier for users to work around problems.  The rest
  is typical driver bugfixes."

* 'i2c/for-current' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux:
  i2c: suppress lockdep warning on delete_device
  i2c: mv64xxx: work around signals causing I2C transactions to be aborted
  i2c: i801: Document feature bits in modinfo
  i2c: designware: add Intel BayTrail ACPI ID
  i2c: designware: always clear interrupts before enabling them
  i2c: designware: fix RX FIFO overrun

Since commit c8801a8e (regulator: core: Mark all get and enable calls as
__must_check) we need to check the value returned by 'regulator_enable()'.

Do this check to get rid of the following build warning:

drivers/staging/imx-drm/imx-tve.c: In function 'imx_tve_probe':
drivers/staging/imx-drm/imx-tve.c:671:19: warning: ignoring return value of 'regulator_enable', declared with attribute warn_unused_result [-Wunused-result]

Without this, I get the following problem when building kernel:

drivers/built-in.o: In function `imx_pd_connector_get_modes':
/linux-2.6/drivers/staging/imx-drm/parallel-display.c:78: undefined reference to `of_get_drm_display_mode'
