iio:inkern: fix overwritten -EPROBE_DEFER in of_iio_channel_get_by_name

2014-10-13T13:41:15+00:00

commit 872687f626e033b4ddfaec1e410057cfc6636d77 upstream.

Fixes: a2c12493ed7e ('iio: of_iio_channel_get_by_name() returns non-null pointers for error legs')

which improperly assumes that of_iio_channel_get_by_name must always
return NULL and thus now hides -EPROBE_DEFER.

iio: adc: ad_sigma_delta: Fix indio_dev->trig assignment

2014-10-13T13:41:14+00:00

commit 9e5846be33277802c0c76e5c12825d0e4d27f639 upstream.

This can result in wrong reference count for trigger device, call
iio_trigger_get to increment reference.

iio: hid_Sensors: fix crash during trigger unregister

2014-10-13T13:41:11+00:00

commit ec7f68e07bf10198717b7824c78201b46bbf1956 upstream.

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.
