| Subject: net: usb: lan78xx: lan78xx_phy_init(): use PHY_POLL instead of "0" if no IRQ is available |
| |
| From: Sven Schuchmann <schuchmann@schleissheimer.de> |
| |
| commit 817b653160db9852d5a0498a31f047e18ce27e5b upstream. |
| |
| On most systems request for IRQ 0 will fail, phylib will print an error message |
| and fall back to polling. To fix this set the phydev->irq to PHY_POLL if no IRQ |
| is available. |
| |
