Jonathan Cameron 79978a9bd0 iio:imu: drop assign iio_info.driver_module and iio_trigger_ops.owner
The equivalent of both of these are now done via macro magic when
the relevant register calls are made.  The actual structure
elements will shortly go away.

Irina Tirdea b1532909de iio: remove unused gpio consumer.h include
GPIO handling code has been removed from the drivers (since
this is now handled by the ACPI core) in commit 0f0796509c ("iio:
remove gpio interrupt probing from drivers that use a single interrupt").

Remove the include for linux/gpio/consumer.h since it is no longer
used.

Adriana Reus 7d0ead5c3f iio: Reconcile operation order between iio_register/unregister and pm functions
At probe, runtime pm should be setup before registering the sysfs interface so
that all the power attributes are accurate and functional when registering.
Also, when removing the device we should unregister first to make sure
that the interfaces that may result in wakeups are no longer available.

Fix this behaviour for the following drivers: bmc150, bmg160, kmx61,
kxcj-1013, mma9551, mma9553, rpr0521.

Octavian Purdila 0f0796509c iio: remove gpio interrupt probing from drivers that use a single interrupt
Commit 845c877009 ("i2c / ACPI: Assign IRQ for devices that have
GpioInt automatically") automatically assigns the first ACPI GPIO
interrupt in client->irq, so we can remove the probing code from
drivers that use only one interrupt.

Octavian Purdila c176becd81 iio: fix drivers that consider 0 as a valid IRQ in client->irq
Since patch "i2c / ACPI: Use 0 to indicate that device does not have
interrupt assigned" [1], 0 is not a valid i2c client irq anymore, so
change all driver's checks accordingly.

The same issue occurs when the device is instantiated via device tree
with no IRQ, or from the i2c sysfs interface, even before the patch
above.

Octavian Purdila 70dddeee89 iio: fix drivers that check buffer->scan_mask
If the in-kernel push interface is used we may have a different masks
on the device buffer and the kernel buffer and in this case the device
should generate data for the reunion of the buffers, which is
available at indio_dev->active_scan_mask.

Compiled tested only except for bmc150-accel which was tested at
runtime with the hardware.

Daniel Baluta 28ff344e1d iio: imu: kmx61: Enhance error handling
This fixes parts of kmx61 error handling to make code easier to read and to be
more consistent with IIO coding conventions:
	* prefer as single point for error handling instead of duplicating code
	for each function
	* directly return a value from a case branch instead of breaking
	* fix error message for writing REG_CTRL1

Also, add separate error paths for kmx61_trigger_setup/iio_triggered_buffer_setup
calls.
