Hi Dmitry,

Those are not generic device functions. They create device managed resource 
so devm_free_irq() is implicitly invoked upon device detach. So replacing 
free_irq() with devm_free_irq() is not very meaningful. There are some 
devm_*() usages in the driver, but it's not used commonly. However, feel 
free to add it.

Regards,
Arend
