iio: imu: Use iio_trigger_get for indio_dev->trig assignment

2015-04-19T08:11:07+00:00

commit 4ce7ca89d6e8eae9e201cd0e972ba323f33e2fb4 upstream.

This patch uses iio_trigger_get to increment the reference
count of trigger device, to avoid incorrect assignment.
Can result in a null pointer dereference during removal if the
trigger has been changed before removal.

This patch refers to a similar situation encountered through the
following discussion:

iio: inv_mpu6050: Clear timestamps fifo while resetting hardware fifo

2015-04-19T08:11:07+00:00

commit 4dac0a8eefd55bb1f157d1a5a084531334a2d74c upstream.

A hardware fifo reset always imply an invalidation of the
existing timestamps, so we'll clear timestamps fifo on
successfull hardware fifo reset.

iio: ad5686: fix optional reference voltage declaration

2015-03-18T12:31:26+00:00

commit da019f59cb16570e78feaf10380ac65a3a06861e upstream.

When not using the "_optional" function, a dummy regulator is returned
and the driver fails to initialize.

iio: imu: adis16400: Fix sign extension

2015-03-18T12:31:25+00:00

commit 19e353f2b344ad86cea6ebbc0002e5f903480a90 upstream.

The intention is obviously to sign-extend a 12 bit quantity. But
because of C's promotion rules, the assignment is equivalent to "val16
&= 0xfff;". Use the proper API for this.

iio:inkern: fix overwritten -EPROBE_DEFER in of_iio_channel_get_by_name

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