2020-01-22drm/amd/display: Call ATOM_INIT instead of ATOM_ENABLE for DMCUBNicholas Kazlauskas
[Why] DMCUB command table doesn't support ATOM_ENABLE/ATOM_DISABLE anymore so we never end up calling the DCN init path in DMCUB.

2020-01-22leds: gpio: Fix uninitialized gpio label for fwnode based probeJacek Anaszewski
When switching to using generic LED name composition mechanism via devm_led_classdev_register_ext() API the part of code initializing struct gpio_led's template name property was removed alongside. It was however overlooked that the property was also passed to devm_fwnode_get_gpiod_from_child() in place of "label" parameter, which when set to NULL, results in gpio label being initialized to '?'. It could be observed in debugfs and failed to properly identify gpio association with LED consumer. Fix this shortcoming by updating the GPIO label after the LED is registered and its final name is known.

2020-01-22net: Fix packet reordering caused by GRO and listified RX cooperationMaxim Mikityanskiy
Commit 323ebb61e32b ("net: use listified RX for handling GRO_NORMAL skbs") introduces batching of GRO_NORMAL packets in napi_frags_finish, and commit 6570bc79c0df ("net: core: use listified Rx for GRO_NORMAL in napi_gro_receive()") adds the same to napi_skb_finish. However, dev_gro_receive (that is called just before napi_{frags,skb}_finish) can also pass skbs to the networking stack: e.g., when the GRO session is flushed, napi_gro_complete is called, which passes pp directly to netif_receive_skb_internal, skipping napi->rx_list. It means that the packet stored in pp will be handled by the stack earlier than the packets that arrived before, but are still waiting in napi->rx_list. It leads to TCP reorderings that can be observed in the TCPOFOQueue counter in netstat. This commit fixes the reordering issue by making napi_gro_complete also use napi->rx_list, so that all packets going through GRO will keep their order. In order to keep napi_gro_flush working properly, gro_normal_list calls are moved after the flush to clear napi->rx_list. iwlwifi calls napi_gro_flush directly and does the same thing that is done by gro_normal_list, so the same change is applied there: napi_gro_flush is moved to be before the flush of napi->rx_list. A few other drivers also use napi_gro_flush (brocade/bna/bnad.c, cortina/gemini.c, hisilicon/hns3/hns3_enet.c). The first two also use napi_complete_done afterwards, which performs the gro_normal_list flush, so they are fine. The latter calls napi_gro_receive right after napi_gro_flush, so it can end up with non-empty napi->rx_list anyway.

2020-01-22can, slip: Protect tty->disc_data in write_wakeup and close with RCURichard Palethorpe
write_wakeup can happen in parallel with close/hangup where tty->disc_data is set to NULL and the netdevice is freed thus also freeing disc_data. write_wakeup accesses disc_data so we must prevent close from freeing the netdev while write_wakeup has a non-NULL view of tty->disc_data. We also need to make sure that accesses to disc_data are atomic. Which can all be done with RCU. This problem was found by Syzkaller on SLCAN, but the same issue is reproducible with the SLIP line discipline using an LTP test based on the Syzkaller reproducer. A fix which didn't use RCU was posted by Hillf Danton.
