clk_imx8mp_audiomix_runtime_resume Kernel panic regression on v6.12

[Francesco Dolcini]

Hello,
it seems that an old regression is back on v6.12, reproduced on -rc2
(not sure about rc1).

The original report is from https://lore.kernel.org/all/20240424164725.GA18760@francesco-nb/
and it was fixed with https://lore.kernel.org/all/1715396125-3724-1-git-send-email-shengjiu.wang@xxxxxxx/.

Is it now back?
