Since the lineevent_state::irq was already set, so\nthe subsequent invocation of free_irq() would trigger the above\nwarning call trace. To fix this issue, set the lineevent_state::irq\nafter the IRQ register successfully."

Dado que lineevent_state::irq ya estaba configurado, la invocaci\u00f3n posterior de free_irq() activar\u00eda el seguimiento de llamada de advertencia anterior. Para solucionar este problema, configure lineevent_state::irq despu\u00e9s del registro IRQ correctamente."
