> Agreed. remove() runs before devres_release_all(), so force_suspend() tears down the hardware while the OF clock provider is still visible. I'll move the runtime PM cleanup into a devm_add_action_or_reset() registered before the clocks/provider, and drop it from remove().
I don't know which email client you are using but you should fix your
client so that the text in your response wraps at 80 characters. Also
add a newline between what you are quoting and your response since it
also makes things much nicer to read in the archive.
