2019-10-11drm/rockchip: Add optional support for CRTC gamma LUTEzequiel Garcia
Add an optional CRTC gamma LUT support, and enable it on RK3288. This is currently enabled via a separate address resource, which needs to be specified in the devicetree. The address resource is required because on some SoCs, such as RK3288, the LUT address is after the MMU address, and the latter is supported by a different driver. This prevents the DRM driver from requesting an entire register space. The current implementation works for RGB 10-bit tables, as that is what seems to work on RK3288.

2019-10-11firmware: google: increment VPD key_len properlyBrian Norris
Commit 4b708b7b1a2c ("firmware: google: check if size is valid when decoding VPD data") adds length checks, but the new vpd_decode_entry() function botched the logic -- it adds the key length twice, instead of adding the key and value lengths separately. On my local system, this means vpd.c's vpd_section_create_attribs() hits an error case after the first attribute it parses, since it's no longer looking at the correct offset. With this patch, I'm back to seeing all the correct attributes in /sys/firmware/vpd/...

2019-10-10net/smc: receive pending data after RCV_SHUTDOWNKarsten Graul
smc_rx_recvmsg() first checks if data is available, and then if RCV_SHUTDOWN is set. There is a race when smc_cdc_msg_recv_action() runs in between these 2 checks, receives data and sets RCV_SHUTDOWN. In that case smc_rx_recvmsg() would return from receive without to process the available data. Fix that with a final check for data available if RCV_SHUTDOWN is set. Move the check for data into a function and call it twice. And use the existing helper smc_rx_data_available().

2019-10-10net/smc: receive returns without dataKarsten Graul
smc_cdc_rxed_any_close_or_senddone() is used as an end condition for the receive loop. This conflicts with smc_cdc_msg_recv_action() which could run in parallel and set the bits checked by smc_cdc_rxed_any_close_or_senddone() before the receive is processed. In that case we could return from receive with no data, although data is available. The same applies to smc_rx_wait(). Fix this by checking for RCV_SHUTDOWN only, which is set in smc_cdc_msg_recv_action() after the receive was actually processed.

2019-10-10drm/amd/display: Program DWB watermarks from correct stateJulian Parkin
[Why] When diags adds a DWB via a stream update, we calculate MMHUBBUB paramaters, but dc->current_state has not yet been updated when the DWB programming happens. This leads to overflow on high bandwidth tests since the incorrect MMHUBBUB arbitration parameters are programmed. [How] Pass the updated context down to the (enable|update)_writeback functions so that they can use the correct watermarks when programming MMHUBBUB.
