This series lays the foundation for changing that design by making clk_register() return an int instead of a struct clk and clkdev/DT lookups take a struct clk_hw instead of a struct clk. After this series is applied, we can avoid using struct clk in provider drivers entirely, unless we want to use the consumer APIs. There are quite a few registration callers, so this change will require converting all of them. I plan to do that gradually over the coming weeks, but I've included a change to qcom platforms because I could easily test it and show how things will work. The first patch is a cleanup to the clkdev APIs that I found while doing this work. I'd like to take that into clk-next with Russell's ack.
