      iio: adc: fix warning in Qualcomm PM8xxx HK/XOADC driver · e0f0ae83
      Linus Torvalds authored
      The pm8xxx_get_channel() implementation is unclear, and causes gcc to
      suddenly generate odd warnings.  The trigger for the warning (at least
      for me) was the entirely unrelated commit 79a4e91d ("device.h: Add
      __cold to dev_<level> logging functions"), which apparently changes gcc
      code generation in the caller function enough to cause this:
      
        drivers/iio/adc/qcom-pm8xxx-xoadc.c: In function ‘pm8xxx_xoadc_probe’:
        drivers/iio/adc/qcom-pm8xxx-xoadc.c:633:8: warning: ‘ch’ may be used uninitialized in this function [-Wmaybe-uninitialized]
          ret = pm8xxx_read_channel_rsv(adc, ch, AMUX_RSV4,
                ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                   &read_nomux_rsv4, true);
                   ~~~~~~~~~~~~~~~~~~~~~~~
        drivers/iio/adc/qcom-pm8xxx-xoadc.c:426:27: note: ‘ch’ was declared here
          struct pm8xxx_chan_info *ch;
                                   ^~
      
      because gcc for some reason then isn't able to see that the termination
      condition for the "for( )" loop in that function is also the condition
      for returning NULL.
      
      So it's not _actually_ uninitialized, but the function is admittedly
      just unnecessarily oddly written.
      
      Simplify and clarify the function, making gcc also see that it always
      returns a valid initialized value.

       "Here is the big driver core patchset for 5.1-rc1
      
        More patches than "normal" here this merge window, due to some work in

        functionality to work better for a number of devices, and independant
        work from Rafael for the device link functionality to make it work
        "correctly".

        The largest thing by far is the new habanalabs driver for their AI

        Other than that, just the usual set of individual driver updates and
        fixes. There's an "odd" merge in here from the DRM tree that they
        asked me to do as the MEI driver is starting to interact with the i915
        driver, and it needed some coordination. All of those patches have
        been properly acked by the relevant subsystem maintainers.

      Pull ARM new SoC family support from Arnd Bergmann:
       "Two new SoC families are added this time.
      
        Sugaya Taichi submitted support for the Milbeaut SoC family from
        Socionext and explains:
      
          "SC2000 is a SoC of the Milbeaut series. equipped with a DSP
           optimized for computer vision. It also features advanced
           functionalities such as 360-degree, real-time spherical stitching
           with multi cameras, image stabilization for without mechanical
           gimbals, and rolling shutter correction. More detail is below:
      
             https://www.socionext.com/en/products/assp/milbeaut/SC2000.html"
      
        Interestingly, this one has a history dating back to older chips made
        by Socionext and previously Matsushita/Panasonic based on their own
        mn10300 CPU architecture that was removed from the kernel last year.
      
        Manivannan Sadhasivam adds support for another SoC family, this is the
        Bitmain BM1880 chip used in the Sophon Edge TPU developer board.
      
        The chip is intended for Deep Learning applications, and comes with
        dual-core Arm Cortex-A53 to run Linux as well as a RISC-V
        microcontroller core to control the tensor unit. For the moment, the
        TPU is not accessible in mainline Linux, so we treat it as a generic
        Arm SoC.

         - Winterland IceBoard is a Texas Instruments AM3874 based machine
           used in telescopes at the south pole and elsewhere, see commit
           d0317731 for some pointers:
      
         - Inspur on5263m5 is an x86 server platform with an Aspeed ast2500
           baseboard management controller. This is for running on the BMC.

         - NVIDIA Shield TV (Darcy) based on Tegra210
      
        And then there are several new SBC, evaluation, development or modular
        systems that we add:
      
         - Three new Rockchips rk3399 based boards:
             - FriendlyElec NanoPC-T4 and NanoPi M4
             - Radxa ROCK Pi 4
      
         - Five new i.MX6 family SoM modules and boards for industrial
           products:
             - Logic PD i.MX6QD SoM and evaluation baseboad
             - Y Soft IOTA Draco/Hydra/Ursa family boards based on i.MX6DL
             - Phytec phyCORE i.MX6 UltraLite SoM and evaluation module
      
         - MYIR Tech MYD-LPC4357 development based on the NXP lpc4357
           microcontroller
      
         - Chameleon96, an Intel/Altera Cyclone5 based FPGA development system
           in 96boards form factor
      
         - Arm Fixed Virtual Platforms(FVP) Base RevC, a purely virtual
           platform for corresponding to the latest "fast model"
      
         - Another Raspberry Pi variant: Model 3 A+, supported both in 32-bit
           and 64-bit mode.
      
         - Oxalis Evalkit V100 based on NXP Layerscape LS1012a, in 96Boards
           enterprise form factor
      
         - Elgin RV1108 R1 development board based on 32-bit Rockchips RV1108
      
        For already supported boards and SoCs, we often add support for new
        devices after merging the drivers. This time, the largest changes
        include updates for
      
         - STMicroelectronics stm32mp1, which was now formally launched last
           week
      
         - Qualcomm Snapdragon 845, a high-end phone and low-end laptop chip
      
         - Action Semi S700
      
         - TI AM654x, their recently merged 64-bit SoC from the OMAP family

         - Samsung s5pv210, used in some older mobile phones
      
        Many other chips see smaller updates and bugfixes beyond that"

      Pull locking updates from Ingo Molnar:
       "The biggest part of this tree is the new auto-generated atomics API
        wrappers by Mark Rutland.
      
        The primary motivation was to allow instrumentation without uglifying
        the primary source code.
      
        The linecount increase comes from adding the auto-generated files to
        the Git space as well:
      
          include/asm-generic/atomic-instrumented.h     | 1689 ++++++++++++++++--
          include/asm-generic/atomic-long.h             | 1174 ++++++++++---
          include/linux/atomic-fallback.h               | 2295 +++++++++++++++++++++++++
          include/linux/atomic.h                        | 1241 +------------
      
        I preferred this approach, so that the full call stack of the (already
        complex) locking APIs is still fully visible in 'git grep'.
      
        But if this is excessive we could certainly hide them.
      
        There's a separate build-time mechanism to determine whether the
        headers are out of date (they should never be stale if we do our job
        right).
      
        Anyway, nothing from this should be visible to regular kernel
        developers.
      
        Other changes:
      
         - Add support for dynamic keys, which removes a source of false
           positives in the workqueue code, among other things (Bart Van
           Assche)
      
         - Updates to tools/memory-model (Andrea Parri, Paul E. McKenney)
      
         - qspinlock, wake_q and lockdep micro-optimizations (Waiman Long)
