Ah, I had not thought of that interface either, so you are probably
right that this is the best way to do it.
Can you send a replacement patch then and add my Reported-by?

I also sent the same patch for drivers/nvmem/meson-efuse.c, which
I guess will also need the same treatment. I also checked and saw
that all three files already had this code in linux-6.0 when
devm_clk_get_enabled() got added.

I can't think of anything that prevents us from using
devm_clk_get_enabled() here.
