iio: st_sensors: Fix indio_dev->trig assignment

2014-10-05T21:52:18+00:00

commit f0e84acd7056e6d7ade551c6439531606ae30a46 upstream.

This can result in wrong reference count for trigger device, call
iio_trigger_get to increment reference.
Refer to http://www.spinics.net/lists/linux-iio/msg13669.html for discussion
with Jonathan.

iio: hid-sensors: Fix power and report state

2013-12-02T21:05:32+00:00

In the original HID sensor hub firmwares all Named array enums were
to 0-based. But the most recent hub implemented as 1-based,
because of the implementation by one of the major OS vendor.
Using logical minimum for the field as the base of enum. So we add
logical minimum to the selector values before setting those fields.
Some sensor hub FWs already changed logical minimum from 0 to 1
to reflect this and hope every other vendor will follow.
There is no easy way to add a common HID quirk for NAry elements,
even if the standard specifies these field as NAry, the collection
used to describe selectors is still just "logical".

iio: hid_Sensors: fix crash during trigger unregister

2013-11-02T19:07:06+00:00

We can't store the trigger instance created by iio_trigger_alloc, in
trig field of iio_device structure. This needs to be stored in the
driver private data. Othewise it can result in crash during module
unload. Hence created a trig_ptr in the common data structure
for each HID sensor IIO driver and storing here.

IIO: call sensor hub open close function

2013-10-01T15:19:08+00:00

Call hid_sensor_hub_device_open when user space opens device and call
hid_sensor_hub_device_close when device is closed. This helps in
saving power.

2013-09-21T18:24:04+00:00

Strip out all those unnecessary gotos and just return the error right away.

Aids to simplicity and reduces code.

iio: sensors-core: st: Support sensors which don't have a Data Ready pin

2013-09-21T18:24:03+00:00

Not all ST's sensors support data ready, so let's make the declaration
of one conditional.

Makes the code a bit shorter and less ugly.
