-Subject: [PATCH] net: allwinner: emac: Add missing free_irq
-
-The sun4i-emac driver uses devm_request_irq at .ndo_open time, but relies on
-the managed device mechanism to actually free it. This causes an issue whenever
-someone wants to restart the interface, the interrupt still being held, and not
-yet released.
-
-Fall back to using the regular request_irq at .ndo_open time, and introduce a
-free_irq during .ndo_stop.
