| Subject: usb: gadget: at91-udc: fix irq and iomem resource retrieval |
| |
| From: Jean-Jacques Hiblot <jjhiblot@traphandler.com> |
| |
| commit 886c7c426d465732ec9d1b2bbdda5642fc2e7e05 upstream. |
| |
| When using dt resources retrieval (interrupts and reg properties) there is |
| no predefined order for these resources in the platform dev resource |
| table. Also don't expect the number of resource to be always 2. |
