In probe the I2C client data is set to the iio_dev struct in probe(), but
assumed to be the tsl2X7X_chip struct in remove(). Fix this by reading the

It is possible that on one of the error paths we are going to try to free
'rxbuf', even though it has not been allocated yet, which cause the following
warning:

drivers/staging/iio/adc/max1363_ring.c:87:7: warning: 'rxbuf' may be used

Only one of the channels of the ade7758 may be sampled at a time. Use the new
validate_scan_mask callback and the iio_validate_scan_mask_onehot function to
implement this restriction. Previously this was implemented using
available_scan_masks, but this requires a individual scan mask for each channel.

implement this restriction. Previously this was implemented using
available_scan_masks, but this requires a individual scan mask for each channel.
Also the previous code was adding the scan index of the timestamp channel to
each available scan mask, this is not required though since the timestamp
channel is not restricted by the available scan masks and can be enabled or
disabled independently. So the new code does not have to take care of this.

The interrupt handler should only ever return one of the three irqreturn_t
constants and not an error code. Also make sure to always call
iio_trigger_notify_done before leaving the trigger handler.

The driver assumes that in 13bit mode the 16bit value has
to be shifted to the right by 3 bits. This is not true, in
both 16bit and 13bit mode the MSB is at the same position.
Currently the driver returns a temperature of 194 degrees
Celsius in 13bit mode and 24 degrees Celsius in 16bit mode.
Fix this by using the same algorithm for 16bit and 13bit
mode and by just masking out the lower three bits in 13bit
mode.

Since commit 1c6c69525b ("genirq: Reject bogus threaded irq requests") threaded
IRQs without a primary handler need to be requested with IRQF_ONESHOT, otherwise
the request will fail. This patch adds the IRQF_ONESHOT to IIO drivers where it
is missing.

The adt7410 expects information about an irq in platform_data.
The driver can work without an irq, so make platform_data optional
by specifying a dummy platform_data if the device has none.

In 13bit mode the lower three bits of the adc value contain
flags. The driver does not use these flags at all, so make 16bit
mode the default.

Reduces code and makes this channel available within the kernel.
Note that it is not added to the buffer, thus maintaining the
previous functionality of this driver.

These were originally introduced when the plan was to have parallel
IIO cores in and out of staging with a slow move between them.
Now we have reached the point where the whole core has moved,
they need clearing up!

The code expects the scan index to match the offset of the channel into the
channel array. For the "shorted" the offset is 3, but the scan index is set to
2. Also the scan index 2 is already taken by the previous channel. As a result
the "shorted" channel will appear to be selected if the previous channel is
selected and vice versa and it is not possible to sample the "shorted" channel
in buffered mode.
