Peter Meerwald f4e2f94d8c iio:kxcjk-1013: Fix endianness in scan_type
driver uses i2c_smbus_read_word_data() to the data in the trigger handler and hence
already does endianness conversion; the I2C chip has data in little endian, but the
value is provides in CPU endianness

Srinivas Pandruvada c1288b8338 iio: accel: kxcjk-1013: Increment ref counter for indio_dev->trig
Assigning indio_dev->trig is not a good idea, as this can result in
wrong reference count for trigger device. If assigned, it is better to
increment reference counter by calling iio_trigger_get.
Refer to http://www.spinics.net/lists/linux-iio/msg13669.html for discussion
with Jonathan.

Srinivas Pandruvada 59bfeaba3b iio: accel: kxcjk-1013: Use try_reenable to ack intr
This chip needs explicit interrupt ack, introducing try_reenable
callback. Also removed separate function to ack interrupt as this
doesn't add any value.

Srinivas Pandruvada 88f6da779a iio: accel: kxcjk1013 Fix missing unlock errors
Fix unlock at two places. One when i2c error occurs and other
when trigger set state when raw read is in progress.
