My motivation for sending [PATCH v4 1/2] irqchip/imx-irqsteer: Convert
to devm_pm_runtime_enable()
https://lore.kernel.org/lkml/aoXZf2z-50H8rimI@lizhi-Precision-Tower-5810/
was the "Unbalanced pm_runtime_enable!"
error during driver unbinding.

This was seen on kernel 6.18, so I would like this error fixed in your
series with a Fixes tag, so stable kernels like 6.18 can be fixed.

Thanks
