If none of the channels are supported, index is 0. Also ensure to return
error code instead of 0 in goto second_mem_fail path.

Pull staging tree update from Greg Kroah-Hartman:
"Here's the big staging tree merge for 3.9-rc1
Lots of cleanups and updates for drivers all through the staging tree.
We are pretty much "code neutral" here, adding just about as many
lines as we removed.
All of these have been in linux-next for a while."

There is a forever loop calling iio_channel_release() because the
"chan < " part of the "chan < ARRAY_SIZE()" is missing. This is in both
the error handling on probe and also in the remove function.
The other thing is that it's possible for some of the elements of the
adc_bat->channel[chan] array to be an ERR_PTR(). I've changed them to be
NULL instead. We're still not allowed to pass NULLs to
iio_channel_release() so I've added a check.
Finally, I removed an unused "chan = ARRAY_SIZE(gab_chan_name);" statement
as a small cleanup.

For iio_channel_get to work with OF based configurations, it needs the
consumer device pointer instead of the consumer device name as argument.

psy->properties is an enum (32 bit type) so adding sizeof() puts us four
times further along than we intended. It should be cast to a char pointer
before doing the math.

On failure, request_any_context_irq() returns a negative value. On
success, it returns either IRQC_IS_HARDIRQ or IRQC_IS_NESTED.

Driver to allow use of the ADC drivers supported by the IIO
subsystem for battery status monitoring. Connecting this
driver to the relevant IIO device requires registration of
the appropriate iio_map structure array by the IIO device
driver (usually from platform data). If specified the driver
will also make use of a gpio to provide interrupt driven
notification that the battery is fully charged.
In last version:
Addressed concerns raised by lars:
a. made the adc_bat per device.
b. get the IIO channel using hardcoded channel names.
c. Minor issues related to gpio_is_valid and some code
refactoring.
In V1:
Addressed concerns raised by Anton:
a. changed the struct name to gab(generic adc battery).
b. Added some functions to neaten the code.
c. Some minor coding guidelines changes.
d. Used the latest function introduce by lars:
iio_read_channel_processed to streamline the code.
In V2:
Addressed concerns by lars:
a. No need of allocating memory for channels.Make it array.
b. Code restructring, coding style and following kernel guidelines changes
suggested by him.
In V3:
Addressed conerns by Anton:
a. Added the copyright.
b. Coding guidelines changes suggested by him.
c. Added Makefile and Kconfig
