Anton Vorontsov 7583605b6d ucc_geth: Fix empty TX queue processing ... Following oops was seen with the ucc_geth driver: Unable to handle kernel paging request for data at address 0x00000058 Faulting instruction address: 0xc024f2fc Oops: Kernel access of bad area, sig: 11 [#1] [...] NIP [c024f2fc] skb_recycle_check+0x14/0x100 LR [e30aa0a4] ucc_geth_poll+0xd8/0x4e0 [ucc_geth_driver] Call Trace: [df857d50] [c000b03c] __ipipe_grab_irq+0x3c/0xa4 (unreliable) [df857d60] [e30aa0a4] ucc_geth_poll+0xd8/0x4e0 [ucc_geth_driver] [df857dd0] [c0258cf8] net_rx_action+0xf8/0x1b8 [df857e10] [c0032a38] __do_softirq+0xb8/0x13c [df857e60] [c00065cc] do_softirq+0xa0/0xac [...] This is because ucc_geth_tx() tries to process an empty queue when queues are logically stopped. Stopping the queues doesn't disable polling, and since nowadays ucc_geth_tx() is actually called from the polling routine, the oops above might pop up. Fix this by removing 'netif_queue_stopped() == 0' check.
