I'm unable to reproduce the issue I was seeing with v6.6-rc3 with and without
the pm_runtime_irq_safe() dropping patch. So AFAIK no issues dropping
pm_runtime_irq_safe().

I was seeing some warning earlier after detaching kernel console and doing
any sysrq trigger on the serial port, seems like it was unrelated.
