sc7180_lpass_dev_resume() returns 'ret' at the end of the function, where 'ret' is always 0. Just return 0 to make it plain obvious that this is always the success path.
Also add an empty line between the error handling path and the return.

Yeah, I noticed this too when I was approving your pick. FWIW, I probably would have written this way, but it's 6 of one and half dozen of the other:
if (ret) dev_err(dev, ...); return ret;
...but I just dug a tiny bit deeper and actually, there's no need for the error print here and it's just wasteful. clk_bulk_prepare_enable() already prints errors for you. So really this whole function could just be:
struct lpass_data *drvdata = dev_get_drvdata(dev); return clk_bulk_prepare_enable(drvdata->num_clks, drvdata->clks);
I guess theoretically one could even go further and look at pm_clk, but perhaps that's overboard.
