Hi Michal, Thank you for sending the patch over! > Simply enable clocks. There is no remove function that's why > this should be enough for simple operation. What clock is this? Would it be worth mentioning what it is for a reference (and for posterity) the commit message? Also why it would need to be enabled and wasn't before? Would this be a fix for some problem? Would this warrant a "Fixes:" tag? And would it need to be back-ported to stable kernels?

Would adding an error check for clk_prepare_enable() and printing an error message using dev_err() be too much in this case? If not, then I would rather follow the pattern that other users established and handle errors as needed. What do you think? Krzysztof
