Revision 2002fbac743b6e2391b4ed50ad9eb626768dd78a authored by Michael Walle on 20 September 2022, 14:16:19 UTC, committed by Jakub Kicinski on 22 September 2022, 13:36:32 UTC
Since commit ece19502834d ("net: phy: micrel: 1588 support for LAN8814
phy") the handler always returns IRQ_HANDLED, except in an error case.
Before that commit, the interrupt status register was checked and if
it was empty, IRQ_NONE was returned. Restore that behavior to play nice
with the interrupt line being shared with others.
