      Pull char/misc driver updates from Greg KH:
       "Here is the big set of new char/misc driver drivers and features for
        4.12-rc1.
      
        There's lots of new drivers added this time around, new firmware
        drivers from Google, more auxdisplay drivers, extcon drivers, fpga
        drivers, and a bunch of other driver updates. Nothing major, except if
        you happen to have the hardware for these drivers, and then you will
        be happy :)
      
        All of these have been in linux-next for a while with no reported
        issues"

        some very minor driver core fixes and changes.

       "Here is the big USB patchset for 4.12-rc1.
      
        Lots of good stuff here, after many many many attempts, the kernel
        finally has a working typeC interface, many thanks to Heikki and
        Guenter and others who have taken the time to get this merged. It
        wasn't an easy path for them at all.
      
        There's also a staging driver that uses this new api, which is why
        it's coming in through this tree.
      
        Along with that, there's the usual huge number of changes for gadget
        drivers, xhci, and other stuff. Johan also finally refactored pretty
        much every driver that was looking at USB endpoints to do it in a
        common way, which will help prevent any "badly-formed" devices from
        causing problems in drivers. That too wasn't a simple task.

      Linus Torvalds authored
      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v4.12 kernel cycle.
      
        Core changes:
      
         - Return NULL from gpiod_get_optional() when GPIOLIB is disabled.
           This was a much discussed change. It affects use cases where people
           write drivers that might or might not be using GPIO resources. I
           have decided that this is the lesser evil right now.
      
         - Make gpiod_count() behave consistently across different hardware
           descriptions.
      
         - Fix the syntax around open drain/open source to not infer active
           high/low semantics.
      
        New drivers:
      
         - A new single-register fixed-direction framework driver for hardware
           that have lines controlled by a single register that just work in
           one direction (out or in), including IRQ support.
      
         - Support the Fintek F71889A GPIO SuperIO controller.
      
         - Support the National NI 169445 MMIO GPIO.
      
         - Support for the X-Gene derivative of the DWC GPIO controller
      
         - Support for the Rohm BD9571MWV-M PMIC GPIO controller.
      
         - Refactor the Gemini GPIO driver to a generic Faraday FTGPIO driver
           and replace both the Gemini and the Moxa ART custom drivers with
           this driver.
      
        Driver improvements:
      
         - A whole slew of drivers have their spinlocks chaned to raw
           spinlocks as they provide irqchips, and thus we are progressing on
           realtime compliance.
      
         - Use devm_irq_alloc_descs() in a slew of drivers, getting managed
           resources.
      
         - Support for the embedded PWM controller inside the MVEBU driver.
      
         - Debounce, open source and open drain support for the Aspeed driver.
      
         - Misc smaller fixes like spelling and syntax and whatnot"

      Pull x86 platform-drivers update from Darren Hart:
       "This represents a significantly larger and more complex set of changes
        than those of prior merge windows.
      
        In particular, we had several changes with dependencies on other
        subsystems which we felt were best managed through merges of immutable
        branches, including one each from input, i2c, and leds. Two patches
        for the watchdog subsystem are included after discussion with Wim and
        Guenter following a collision in linux-next (this should be resolved
        and you should only see these two appear in this pull request). These

      cfg80211: make RATE_INFO_BW_20 the default · 842be75c
      Johannes Berg authored
      Due to the way I did the RX bitrate conversions in mac80211 with
      spatch, going setting flags to setting the value, many drivers now
      don't set the bandwidth value for 20 MHz, since with the flags it
      wasn't necessary to (there was no 20 MHz flag, only the others.)
      
      Rather than go through and try to fix up all the drivers, instead
      renumber the enum so that 20 MHz, which is the typical bandwidth,
      actually has the value 0, making those drivers all work again.
      
      If VHT was hit used with a driver not reporting it, e.g. iwlmvm,
      this manifested in hitting the bandwidth warning in
      cfg80211_calculate_bitrate_vht().

      ipv6: initialize route null entry in addrconf_init() · 2f460933
      WANG Cong authored
      Andrey reported a crash on init_net.ipv6.ip6_null_entry->rt6i_idev
      since it is always NULL.
      
      This is clearly wrong, we have code to initialize it to loopback_dev,
      unfortunately the order is still not correct.
      
      loopback_dev is registered very early during boot, we lose a chance
      to re-initialize it in notifier. addrconf_init() is called after
      ip6_route_init(), which means we have no chance to correct it.
      
      Fix it by moving this initialization explicitly after
      ipv6_add_dev(init_net.loopback_dev) in addrconf_init().

      rtnetlink: NUL-terminate IFLA_PHYS_PORT_NAME string · 77ef033b
      Michal Schmidt authored
      IFLA_PHYS_PORT_NAME is a string attribute, so terminate it with \0.
      Otherwise libnl3 fails to validate netlink messages with this attribute.
      "ip -detail a" assumes too that the attribute is NUL-terminated when
      printing it. It often was, due to padding.
      
      I noticed this as libvirtd failing to start on a system with sfc driver
      after upgrading it to Linux 4.11, i.e. when sfc added support for
      phys_port_name.

      forcedeth: remove unnecessary carrier status check · 5d826b7b
      Zhu Yanjun authored
      Since netif_carrier_on() will do nothing if device's
      carrier is already on, so it's unnecessary to do
      carrier status check.
      
      It's the same for netif_carrier_off().

      Pull tracing updates from Steven Rostedt:
       "New features for this release:
      
         - Pretty much a full rewrite of the processing of function plugins.
           i.e. echo do_IRQ:stacktrace > set_ftrace_filter
      
         - The rewrite was needed to add plugins to be unique to tracing
           instances. i.e. mkdir instance/foo; cd instances/foo; echo
           do_IRQ:stacktrace > set_ftrace_filter The old way was written very
           hacky. This removes a lot of those hacks.
      
         - New "function-fork" tracing option. When set, pids in the
           set_ftrace_pid will have their children added when the processes
           with their pids listed in the set_ftrace_pid file forks.
      
         - Exposure of "maxactive" for kretprobe in kprobe_events
      
         - Allow for builtin init functions to be traced by the function
           tracer (via the kernel command line). Module init function tracing
           will come in the next release.
      
         - Added more selftests, and have selftests also test in an instance"

      Pull printk updates from Petr Mladek:
      
       - There is a situation when early console is not deregistered because
         the preferred one matches a wrong entry. It caused messages to appear
         twice.
      
         This is the 2nd attempt to fix it. The first one was wrong, see the
         commit c6c7d83b ('Revert "console: don't prefer first registered
         if DT specifies stdout-path"').
      
         The fix is coupled with some small code clean up. Well, the console
         registration code would deserve a big one. We need to think about it.
      
       - Do not lose information about the preemtive context when the console
         semaphore is re-taken.
      
       - Do not block CPU hotplug when someone else is already pushing
         messages to the console.
