iio: adis16400: Compute the scan mask from channel indices

2015-06-23T12:55:09+00:00

commit c2a8b623a089d52c199e305e7905829907db8ec8 upstream.

We unfortunately can't use ~0UL for the scan mask to indicate that the
only valid scan mask is all channels selected. The IIO core needs the exact
mask to work correctly and not a super-set of it. So calculate the masked
based on the channels that are available for a particular device.

iio: adis16400: Use != channel indices for the two voltage channels

2015-06-23T12:55:09+00:00

commit 7323d59862802ca109451eeda9777024a7625509 upstream.

Previously, the two voltage channels had the same ID, which didn't cause
conflicts in sysfs only because one channel is named and the other isn't;
this is still violating the spec though, two indexed channels should never
have the same index.

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

2015-04-22T06:58:39+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

2015-04-22T06:58:38+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.

and the driver fails to initialize.

iio: imu: adis16400: Fix sign extension

2015-03-12T10:10:05+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.
