[PATCH 0/3] iio: adc: xilinx-ams: refactor alarm handling to table-driven design

[Guilherme Ivo Bozi]

This series addresses significant code duplication in alarm handling
logic across the Xilinx AMS IIO driver.

An analysis of the codebase (ArKanjo explorer) revealed multiple
duplicated mappings between scan_index, alarm bits, and register
offsets.

To address this, the series introduces a centralized table-driven
mapping (alarm_map) that replaces multiple switch statements spread
across the driver.

This improves:
- maintainability (single source of truth for mappings)
- readability (removes repeated switch logic)
- extensibility (new alarms require only table updates)

No functional changes are intended.

Series overview:
- Patch 1: fix out-of-bounds channel lookup 
- Patch 2: convert mutex handling to guard(mutex) 
- Patch 3: introduce table-driven alarm mapping
