| Doc Text: |
Previously, if a device disappeared and then reappeared, the "irq_count" interrupt request (IRQ) counter in irqbalance overflowed, which resulted in a failure to balance IRQs. This update adds a check which triggers a rescan of the IRQ database if the counter decreases. As a result, IRQs remain correctly balanced for disappearing and reappearing devices.
