Change request_irq to devm_request_irq and free_irq to devm_free_irq. It's better to change the code this way.
Why? What did this fix up? You still are manually requesting and freeing the irq. What bug did you fix?
The IRQF_SHARED interrupt flag was added because an interrupt error was detected when the serial port was opened twice in a row on the project.
That is a different change. Make that a different patch. thanks, greg k-h _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
