Statically allocated array of pointed to hwmon_channel_info can be made const for safety. Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski at linaro.org> --- This depends on hwmon core patch: https://lore.kernel.org/all/20230406203103.3011503-2-krzysztof.kozlowski at linaro.org/ Therefore I propose this should also go via hwmon tree.
