devm_gpio_request is device managed and makes error handling and exit code
simpler.

With cleanup to hdmi_resources_init, we can remove hdmi_resource_cleanup
function. So could you please re-send updated patches?

You've been submitting patches into too small pieces.
Because they are trivial enough and in the same context, please merge this
kind of patches as long as they are related with the same class or topics. I
think you can combine them. :)

Thanks,
Inki Dae

OK. I will update and re-send.

Generally, the accepted practice is to combine patches if they do
similar changes in the same file.
Else, separate patches is preferred as it makes things easier for
reviewers and maintainer by improving readability and less rework
effort.
Since you have specifically requested for combining the patches I will
squash patches related to clk_get together and resend the series.
