Himanshu Jha a937729c93 iio: potentiometer: ds1803: Remove VLA usage
In preparation to enabling -Wvla, remove VLA usage and replace it
with fixed a fixed length array and therefore, prevent potential
stack overflow attacks.

Fixed as a part of the discussion to remove all VLAs from the kernel:

Jonathan Cameron 6d9d020da5 iio:dpot: drop assign iio_info.driver_module
The equivalent of this is now done via macro magic when
the relevant register call is made.  The actual structure
elements will shortly go away.
