commit 6db053cd949fcd6254cea9f2cd5d39f7bd64379c upstream.

Commit 4c3577db3e ("Staging: iio: impedance-analyzer: Fix sparse
warning") fixed a compiler warning, but introduced a bug that resulted
in one of the two 16 bit IIO channels always being zero (when both are
enabled).

This is because int is 32 bits wide on most architectures and in the
case of a little-endian machine the two most significant bytes would
occupy the buffer for the second channel as 'val' is being passed as a
void pointer to 'iio_push_to_buffers()'.

Fix by defining 'val' as u16. Tested working on ARM64.
