Subject: staging:iio: Remove deprecated dev_data from iio_dev.
X-Git-Tag: MMI-PSA29.97-13-9~18234^2^2~864^2~230
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4024bc73b1d1d8f82518b67b0996cb7b870dd1d4;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

staging:iio: Remove deprecated dev_data from iio_dev.

The equivalent should always be done using iio_alllocate_device
with to create a private area for the driver and then iio_priv
to access it.  There may be other uses for a private data pointer
but right now it just leads driver writers astray.
