2018-01-18i2c: rk3x: account for const type of of_device_id.dataJulia Lawall
This driver creates a number of const structures that it stores in the data field of an of_device_id array. The data field of an of_device_id structure has type const void *, so there is no need for a const-discarding cast when putting const values into such a structure. Furthermore, adding const to the declaration of the location that receives a const value from such a field ensures that the compiler will continue to check that the value is not modified. The const-discarding cast on the extraction from the data field is thus no longer needed. Done using Coccinelle.

This is a series of patches, some of them initially by Franklin S Cooper Jr, which was picked up by Faiz Abbas. Faiz Abbas added some patches while working on this series, I contributed one as well. The first two patches add support to CAN device infrastructure to limit the bitrate of a CAN adapter if the used CAN-transceiver has a certain maximum bitrate. The remaining patches improve the m_can driver. They add support for bitrate limiting to the driver, clean up the driver and add support for runtime PM. ==================== Signed-off-by: David S.

2018-01-17ubi: fastmap: Erase outdated anchor PEBs during attachSascha Hauer
The fastmap update code might erase the current fastmap anchor PEB in case it doesn't find any new free PEB. When a power cut happens in this situation we must not have any outdated fastmap anchor PEB on the device, because that would be used to attach during next boot. The easiest way to make that sure is to erase all outdated fastmap anchor PEBs synchronously during attach.

2018-01-17r8152: disable RX aggregation on Dell TB16 dockKai-Heng Feng
r8153 on Dell TB15/16 dock corrupts rx packets. This change is suggested by Realtek. They guess that the XHCI controller doesn't have enough buffer, and their guesswork is correct, once the RX aggregation gets disabled, the issue is gone. ASMedia is currently working on a real sulotion for this issue. Dell and ODM confirm the bcdDevice and iSerialNumber is unique for TB16. Note that TB15 has different bcdDevice and iSerialNumber, which are not unique values. If you still have TB15, please contact Dell to replace it with TB16.

2018-01-17tun: fix a memory leak for tfile->tx_arrayCong Wang
tfile->tun could be detached before we close the tun fd, via tun_detach_all(), so it should not be used to check for tfile->tx_array. As Jason suggested, we probably have to clean it up unconditionally both in __tun_deatch() and tun_detach_all(), but this requires to check if it is initialized or not. Currently skb_array_cleanup() doesn't have such a check, so I check it in the caller and introduce a helper function, it is a bit ugly but we can always improve it in net-next.

2018-01-17bnxt_en: export a common switchdev PARENT_ID for all reps of an adapterSathya Perla
Currently the driver exports different switchdev PARENT_IDs for representors belonging to different SR-IOV PF-pools of an adapter. This is not correct as the adapter can switch across all vports of an adapter. This patch fixes this by exporting a common switchdev PARENT_ID for all reps of an adapter. The PCIE DSN is used as the id. Signed-off-by: Sathya Perla <sathya.perla@broadcom.com> Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
