| Subject: usbnet: fix status interrupt urb handling |
| |
| From: Felix Fietkau <nbd@openwrt.org> |
| |
| [ Upstream commit 52f48d0d9aaa621ffa5e08d79da99a3f8c93b848 ] |
| |
| Since commit 7b0c5f21f348a66de495868b8df0284e8dfd6bbf |
| "sierra_net: keep status interrupt URB active", sierra_net triggers |
| status interrupt polling before the net_device is opened (in order to |
| properly receive the sync message response). |
| |
| To be able to receive further interrupts, the interrupt urb needs to be |
| re-submitted, so this patch removes the bogus check for netif_running(). |
