That is required in case there is a need to iterate these clocks later, therefore I couldn't see any use case of this parameter and should have been simply removed from the function declaration. The first patch in the series provides devm_clk_bulk_get_all_enabled() variant, which is consistent with devm_clk_bulk_get_all() in terms of the returned value: > 0 if one or more clocks have been stored = 0 if there are no clocks < 0 if an error occurred Moreover, the naming is consistent with devm_clk_get_enabled(), i.e. use the past form of 'enable'. The next two patches switch existing users of devm_clk_get_enable() to the new helper - there were only two, as of next-20240913. The last patch drops the now obsolete devm_clk_bulk_get_all_enable() helper.
