| Subject: [PATCH] phy: renesas: rcar-gen3-usb2: Use platform_get_irq_optional() |
| for optional irq |
| |
| commit b049e03ca57f238e74a79e44ffc85904db465e72 upstream. |
| |
| As platform_get_irq() now prints an error when the interrupt does not |
| exist, a scary warning may be printed for an optional interrupt: |
| |
| phy_rcar_gen3_usb2 ee0a0200.usb-phy: IRQ index 0 not found |
| |
| Fix this by calling platform_get_irq_optional() instead. |
| |
| Fixes: 7723f4c5ecdb8d83 ("driver core: platform: Add an error message to platform_get_irq*()") |
