From: Minghao Chi <chi.minghao@xxxxxxxxxx> Calling synchronize_irq() right before free_irq() is quite useless. On one hand the IRQ can easily fire again before free_irq() is entered, on the other hand free_irq() itself calls synchronize_irq() internally (in a race condition free way) before any state associated with the IRQ is freed.
