From: Marco Pagani <marpagan@xxxxxxxxxx>
commit 6794ed0cfcc6ce737240eccc48b3e8190df36703 upstream.
The clang-analyzer reported a warning: "Value stored to 'ret'
is never read".
Fix the return value check if devm_krealloc() fails to resize
ams_channels.
Fixes: d5c70627a794 ("iio: adc: Add Xilinx AMS driver")
