Thanks, Bart.

You mean it should be: hwmon_channel_info *const ufs_hwmon_info ? I think the pointer * is tied only to variable name, but not to const. Majority seems to choose similarly: git grep "\*const" | wc -l 2763 git grep "\* const" | wc -l 16204 But if this is more than a nit, but your preference, I can fix it. Best regards, Krzysztof

This can only result in chaos. The dependent patch is available at git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging.git hwmon-const or wait until after the next commit window to apply this patch.

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