In previous patch you renamed from ABC123_ to WLED3_, now you are renaming back to WLED? Stop messing with the names. I'd actually prefer you to stick with original driver name, and just add note that this now supports more hardware. But yes, _one_ rename is okay. I guess. But renaming it twice in one series is not acceptable. > @@ -365,6 +433,15 @@ static int wled_configure(struct wled *wled, struct device *dev) > > cfg->num_strings = cfg->num_strings + 1; > > + string_len = of_property_count_elems_of_size(dev->of_node, > + "qcom,enabled-strings", > + sizeof(u32)); > + if (string_len > 0) > + rc = of_property_read_u32_array(dev->of_node, > + "qcom,enabled-strings", > + wled->cfg.enabled_strings, > + sizeof(u32)); > + > return 0; > } rc is assigned but never used.
