      Pull LED updates from Pavel Machek:
       "Okay, so... this one is interesting. RGB LEDs are very common, and we
        need to have some kind of support for them. Multicolor is for
        arbitrary set of LEDs in one package, RGB is for LEDs that can produce
        full range of colors. We do not have real multicolor LED that is not
        RGB in the pipeline, so that one is disabled for now.

      ====================
      misc bug fixes for the hso driver
      
      1. Code reuse led to an unregistration of a net driver that has not been
      registered
      2. The kernel complains generically if kmalloc with GFP_KERNEL fails
      3. A race that can lead to an URB that is in use being reused or
      a use after free

      hso: fix bailout in error case of probe · 5fcfb6d0
      Oliver Neukum authored
      The driver tries to reuse code for disconnect in case
      of a failed probe.
      If resources need to be freed after an error in probe, the
      netdev must not be freed because it has never been registered.
      Fix it by telling the helper which path we are in.

         - Report the size of the page table mapping out of hmm_range_fault().
      
           This makes it easier to establish a large/huge/etc mapping in the
           device's page table.
      
         - Allow devices to ignore the invalidations during migration in cases
           where the migration is not going to change pages.
      
           For instance migrating pages to a device does not require the
           device to invalidate pages already in the device.
      
         - Update nouveau and hmm_tests to use the above"

      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v5.9 kernel cycle.
      
        There is nothing too exciting in it, but a new macro that fixes a
        build failure on a minor ARM32 platform that appeared yesterday is
        part of it so we better merge it.
      
        Core changes:
      
         - Introduce the for_each_requested_gpio() macro to help in dependent
           code all over the place. Also patch a few locations to use it while
           we are at it.
      
         - Split out the sysfs code into its own file.
      
         - Split out the character device code into its own file, then make a
           set of refactorings and improvements to this code. We are setting
           the stage to revamp the userspace API a bit in the next cycle.
      
         - Fix a whole slew of kerneldoc that was wrong or missing.
      
        New drivers:
      
         - The PCA953x driver now supports the PCAL9535.
      
        Driver improvements:
      
         - A host of incremental modernizations and improvements to the
           PCA953x driver.
      
         - Incremental improvements to the Xilinx Zynq driver.
      
         - Some improvements to the GPIO aggregator driver.
      
         - I ran all over the place switching all threaded and other drivers
           requesting their own IRQ while using the core GPIO IRQ helpers to
           pass the GPIO irq chip as a template instead of calling the
           explicit set-up functions. Next merge window we may retire the old

      selftests/net: relax cpu affinity requirement in msg_zerocopy test · 16f6458f
      Willem de Bruijn authored
      The msg_zerocopy test pins the sender and receiver threads to separate
      cores to reduce variance between runs.
      
      But it hardcodes the cores and skips core 0, so it fails on machines
      with the selected cores offline, or simply fewer cores.
      
      The test mainly gives code coverage in automated runs. The throughput
      of zerocopy ('-z') and non-zerocopy runs is logged for manual
      inspection.
      
      Continue even when sched_setaffinity fails. Just log to warn anyone
      interpreting the data.

      The MPTCP protocol is trying to create a subflow for an

      Unaccepted sockets have still a NULL sk_socket field,
      avoid the issue by failing earlier.

      ====================
      selftests: rtnetlink: Fix for false-negative return values
      
      This patchset will address the false-negative return value issue
      caused by the following:
        1. The return value "ret" in this script will be reset to 0 from
           the beginning of each sub-test in rtnetlink.sh, therefore this
           rtnetlink test will always pass if the last sub-test has passed.
        2. The test result from two sub-tests in kci_test_encap() were not
           being processed, thus they will not affect the final test result
           of this test.

      kci_test_encap() is actually composed by two different sub-tests,
      kci_test_encap_vxlan() and kci_test_encap_fou()
      
      Therefore we should check the test result of these two in
      kci_test_encap() to let the script be aware of the pass / fail status.
      Otherwise it will generate false-negative result like below:

      net: dsa: sja1105: use detected device id instead of DT one on mismatch · 0b0e2997
      Vladimir Oltean authored
      Although we can detect the chip revision 100% at runtime, it is useful
      to specify it in the device tree compatible string too, because
      otherwise there would be no way to assess the correctness of device tree
      bindings statically, without booting a board (only some switch versions
      have internal RGMII delays and/or an SGMII port).
      
      But for testing the P/Q/R/S support, what I have is a reworked board
      with the SJA1105T replaced by a pin-compatible SJA1105Q, and I don't
      want to keep a separate device tree blob just for this one-off board.
      Since just the chip has been replaced, its RGMII delay setup is
      inherently the same (meaning: delays added by the PHY on the slave
      ports, and by PCB traces on the fixed-link CPU port).
      
      For this board, I'd rather have the driver shout at me, but go ahead and
      use what it found even if it doesn't match what it's been told is there.

      tipc: set ub->ifindex for local ipv6 address · 5a6f6f57
      Xin Long authored
      Without ub->ifindex set for ipv6 address in tipc_udp_enable(),
      ipv6_sock_mc_join() may make the wrong dev join the multicast
      address in enable_mcast(). This causes that tipc links would
      never be created.
      
      So fix it by getting the right netdev and setting ub->ifindex,
      as it does for ipv4 address.

      This reverts commit 71130f29.
      
      In commit 71130f29 ("vxlan: fix tos value before xmit") we want to
      make sure the tos value are filtered by RT_TOS() based on RFC1349.
      
             0     1     2     3     4     5     6     7
          +-----+-----+-----+-----+-----+-----+-----+-----+
          |   PRECEDENCE    |          TOS          | MBZ |
          +-----+-----+-----+-----+-----+-----+-----+-----+
      
      But RFC1349 has been obsoleted by RFC2474. The new DSCP field defined like
      
             0     1     2     3     4     5     6     7

          +-----+-----+-----+-----+-----+-----+-----+-----+
      
      So with
      
      IPTOS_TOS_MASK          0x1E
      RT_TOS(tos)		((tos)&IPTOS_TOS_MASK)
      
      the first 3 bits DSCP info will get lost.
      
      To take all the DSCP info in xmit, we should revert the patch and just push
      all tos bits to ip_tunnel_ecn_encap(), which will handling ECN field later.

        using the changes, for 5.9-rc1.
      
        "Biggest" thing in here is the device link exposure in sysfs, to help
        to tame the madness that is SoC device tree representations and driver
        interactions with it.
      
        Other stuff in here that is interesting is:
      
         - device probe log helper so that drivers can report problems in a
           unified way easier.
      
         - devres functions added
      
         - DEVICE_ATTR_ADMIN_* macro added to make it harder to write
           incorrect sysfs file permissions
      
         - documentation cleanups
      
         - ability for debugfs to be present in the kernel, yet not exposed to
           userspace. Needed for systems that want it enabled, but do not
           trust users, so they can still use some kernel functions that were
           otherwise disabled.
      
         - other minor fixes and cleanups
      
        The patches outside of drivers/base/ all have acks from the respective
        subsystem maintainers to go through this tree instead of theirs.
      
        All of these have been in linux-next with no reported issues"

      MAINTAINERS: update phylink/sfp keyword matching · 22fcffeb
      Russell King authored
      syzbot has revealed that the "phylink" keyword exists in non-phylink
      related contexts in the bluetooth stack. To avoid receiving
      inappropriate notifications, change the keyword matching regexp to
      something which avoids this, while still allowing changes to networking
      drivers that make use of phylink to be detected.
