2019-09-05net/mlx5: fix missing assignment of variable errColin Ian King
The error return from a call to mlx5_flow_namespace_set_peer is not being assigned to variable err and hence the error check following the call is currently not working.

2019-09-05r8152: adjust the settings of ups flagsHayes Wang
The UPS feature only works for runtime suspend, so UPS flags only need to be set before enabling runtime suspend. Therefore, I create a struct to record relative information, and use it before runtime suspend. All chips could record such information, even though not all of them support the feature of UPS. Then, some functions could be combined. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2019-09-05Merge branch 'gianfar-some-assorted-cleanup'David S. Miller
Arseny Solokha says: ==================== gianfar: some assorted cleanup This is a cleanup series for the gianfar Ethernet driver, following up a discussion in [1]. It is intended to precede a conversion of gianfar from PHYLIB to PHYLINK API, which will be submitted later in its version 2. However, it won't make a conversion cleaner, except for the last patch in this series. Obviously this series is not intended for -stable. The first patch looks super controversial to me, as it moves lots of code around for the sole purpose of getting rid of static forward declarations in two translation units. On the other hand, this change is purely mechanical and cannot do any harm other than cluttering git blame output. I can prepare an alternative patch for only swapping adjacent functions around, if necessary. The second patch is a trivial follow-up to the first one, making functions that are only called from the same translation unit static. The third patch removes some now unused macro and structure definitions from gianfar.h, slipped away from various cleanups in the past. The fourth patch, also suggested in [1], makes the driver consistently use PHY connection type value obtained from a Device Tree node, instead of ignoring it and using the one auto-detected by MAC, when connecting to PHY. Obviously a value has to be specified correctly in DT source, or omitted altogether, in which case the driver will fall back to auto-detection. When querying a DT node, the driver will also take both applicable properties into account by making a proper API call instead of open-coding the lookup half-way correctly.

2019-09-05gianfar: use DT more consistently when selecting PHY connection typeArseny Solokha
Historically, gianfar only used phy-connection-type DT property when connected to PHY in the rgmii-id mode. It ignored the property otherwise, relying on the connection type auto-detection carried out by MAC and providing that reconstructed mode to of_phy_connect(). It also did not consider alternative phy-mode property at all. Make the driver properly query DT node for PHY connection type first and use an obtained value if it was specified there. Otherwise, if a particular DT relies on connection type auto-detection, fall back to reconstructing the value from MAC registers, as before.

The next three patches are also by me and they introduce and make use of the CAN midlayer private structure. It is used to hold protocol specific per device data structures. The next patch is by Oleksij Rempel, switches the &net->can.rcvlists_lock from a spin_lock() to a spin_lock_bh(), so that it can be used from NAPI (soft IRQ) context. The next 4 patches are by Kurt Van Dijck, he first updates his email address via mailmap and then extends sockaddr_can to include j1939 members. The final patch is the collective effort of many entities (The j1939 authors: Oliver Hartkopp, Bastian Stender, Elenita Hinds, kbuild test robot, Kurt Van Dijck, Maxime Jayat, Robin van der Gracht, Oleksij Rempel, Marc Kleine-Budde). It adds support of SAE J1939 protocol to the CAN networking stack. SAE J1939 is the vehicle bus recommended practice used for communication and diagnostics among vehicle components.
