[PATCH 1/3] iio: adc: xilinx-ams: fix out-of-bounds channel lookup in event handling

[Guilherme Ivo Bozi]

> ams_event_to_channel() may return a pointer past the end of
> dev->channels when no matching scan_index is found. This can lead
> to invalid memory access in ams_handle_event().
>
> Add a bounds check in ams_event_to_channel() and return NULL when
> no channel is found. Also guard the caller to safely handle this
> case.
