These new functions allow sparse to find failures to release

A follow up set may move those calls over to a sparse friendly

3b5b55ca94 iio: adc: ad7606: dynamically allocate channel info 
Refactor the ad7606 drivers to dynamically allocate the channel info.

The channel info was getting a bit unwieldy. In some cases, the
indio_dev->channels field was getting assigned up to 3 different times,
each in a different function, making it difficult to see where the info
was coming from. This problem stems from the number of permutations of
the channel array needed to support various modes of operation and data
buses. We already have 4 per chip (hardware mode, software mode, AXI ADC
backend and AXI ADC backend with software mode) and we intend to add two
more per chip when adding SPI offload support.

To make it easier to read and maintain, move all of the channel setup
to a single function that dynamically allocates and fills in the channel
info.

Additionally, this lets us remove some hacks where we had to compute an
offset due to the fact that sometimes there was a soft timestamp channel
at the start of the array. Now the timestamp channel is always at the
end of the array as is typical in other drivers.

3f57a3b9ab iio: adc: Support ROHM BD79124 ADC 
The ROHM BD79124 is a 12-bit, 8-channel, SAR ADC. The ADC supports
an automatic measurement mode, with an alarm interrupt for out-of-window
measurements. The window is configurable for each channel.

The I2C protocol for manual start of the measurement and data reading is
somewhat peculiar. It requires the master to do clock stretching after
sending the I2C slave-address until the slave has captured the data.
Needless to say this is not well suopported by the I2C controllers.

Thus do not support the BD79124's manual measurement mode but implement
the measurements using automatic measurement mode, relying on the
BD79124's ability of storing latest measurements into register.

Support also configuring the threshold events for detecting the
out-of-window events.

The BD79124 keeps asserting IRQ for as long as the measured voltage is
out of the configured window. Thus, prevent the user-space from choking
on the events and mask the received event for a fixed duration (1 second)
when an event is handled.

The ADC input pins can be also configured as general purpose outputs.
Make those pins which don't have corresponding ADC channel node in the
device-tree controllable as GPO.

19d8a86918 iio: adc: sun20i-gpadc: Use adc-helpers 
The new devm_iio_adc_device_alloc_chaninfo_se() -helper is intended to
help drivers avoid open-coding the for_each_node -loop for getting the
channel IDs. The helper provides standard way to detect the ADC channel
nodes (by the node name), and a standard way to convert the "reg"
-properties to channel identification numbers, used in the struct
iio_chan_spec. Furthermore, the helper can optionally check the found
channel IDs are smaller than given maximum. This is useful for callers
which later use the IDs for example for indexing a channel data array.

The original driver treated all found child nodes as channel nodes. The
new helper requires channel nodes to be named channel[@N]. This should
help avoid problems with devices which may contain also other but ADC
child nodes. Quick grep from arch/* with the sun20i-gpadc's compatible
string didn't reveal any in-tree .dts with channel nodes named
otherwise. Also, same grep shows all the in-tree .dts seem to have
channel IDs between 0..num of channels.

Use the new helper.
