[PATCH] iio:accel:adis16201: Fix wrong axis assignment that prevents loading

[PATCH] iio:accel:adis16201: Fix wrong axis assignment that prevents loading

[Jonathan Cameron]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Whilst running some basic tests as part of writing up the dt-bindings for
this driver (to follow), it became clear it doesn't actually load
currently.

iio iio:device1: tried to double register : in_incli_x_index
adis16201 spi0.0: Failed to create buffer sysfs interfaces
adis16201: probe of spi0.0 failed with error -16

Looks like a cut and paste / update bug.  Fixes tag obviously not accurate
but we don't want to bother carry thing back to before the driver moved
out of staging.

Give this has been broken a while I'm not going to rush it it as a
fix.  Applied to the togreg branch of iio.git and pushed out as testing
for the autobuilders to poke at it.

Thanks,

Jonathan
