| Subject: [PATCH] ath79: ignore the abused interrupt-map on pcie node
 | |
| 
 | |
| ath79 PCIe interrupt controller has stopped working correctly. This
 | |
| is because the DT exposing a non-sensical interrupt-map property,
 | |
| and their drivers relying on the kernel ignoring this property[1].
 | |
| 
 | |
| This patch fix the pcie init error:
 | |
| ath9k 0000:00:00.0: of_irq_parse_pci: failed with rc=-14
 | |
| 
 | |
| Notice:
 | |
| This is just a workaround, not a fix. PCIe driver and related dts
 | |
| node need to be rewritten.
