I think it would be better to call those functions somewhere instead, e.g. in the fimc-is initialization routine, until there is a user interface available for this 3A control. fimc_is_hw_set_tune() just needs a private control a think. Let me see if I can come up with at least some intermediate patch to achieve this, so the warnings can be eliminated. I wouldn't like to take such steps backwards, marking those functions static an unused.

However if you can come up with some users for these functions, then that would be great and right thing to do.

__is_set_init_isp_aa and fimc_is_hw_set_tune currently do not have any callers. However these functions may be used in the future. Hence instead of deleting them, staticize and annotate them with __maybe_unused flag to avoid compiler warnings.
