In local_bh_enable() there is a WARN_ON(irqs_disabled()), but looking at the rest of the code, it seems it expects to be used with interrupts off, so is this warning really necessary? I hit this warning in the ads7846 touchscreen driver timer function where enable_irq() may be called with interrupts disabled. Since enable_irq now calls local_bh_disable/enable for IRQ resend, this warning is triggered.
