      Merge media fixes from Mauro Carvalho Chehab:
       "This contains two patches fixing problems with my patch series meant
        to make USB drivers to work again after the DMA on stack changes.
      
        The last patch on this series is actually not related to DMA on stack.
        It solves a longstanding bug affecting module unload, causing
        module_put() to be called twice. It was reported by the user who
        reported and tested the issues with the gp8psk driver with the DMA
        fixup patches. As we're late at -rc cycle, maybe you prefer to not
        apply it right now. If this is the case, I'll add to the pile of
        patches for 4.10.
      
        Exceptionally this time, I'm sending the patches via e-mail, because
        I'm on another trip, and won't be able to use the usual procedure
        until Monday. Also, it is only three patches, and you followed already
        the discussions about the first one"

      gp8psk: Fix DVB frontend attach · 7a0786c1
      Mauro Carvalho Chehab authored
      The DVB binding schema at the DVB core assumes that the frontend is a
      separate driver.  Faling to do that causes OOPS when the module is
      removed, as it tries to do a symbol_put_addr on an internal symbol,
      causing craches like:

      The ns->lba_shift assumes its value to be the logarithmic of the
      LA size. A previous patch duplicated the lba_shift calculation into
      lightnvm. It prematurely also subtracted a 512byte shift, which commonly
      is applied per-command. The 512byte shift being subtracted twice led to
      data loss when restoring the logical to physical mapping table from
      device and when issuing I/O commands using rrpc.
      
      Fix offset by removing the 512byte shift subtraction when calculating
      lba_shift.

      Linus Torvalds authored
      Merge fixes for -Wmaybe-uninitialized from Arnd Bergmann:
       "It took a while for some patches to make it into mainline through
        maintainer trees, but the 28-patch series is now reduced to 10, with
        one tiny patch added at the end.
      
        Aside from patches that are no longer required, I did these changes
        compared to version 1:
      
         - Dropped "iio: maxim_thermocouple: detect invalid storage size in
           read()", which is currently in linux-next as commit 32cb7d27.
           This is the only remaining warning I see for a couple of corner
           cases (kbuild bot reports it on blackfin, kernelci bot and arm-soc
           bot both report it on arm64)
      
         - Dropped "brcmfmac: avoid maybe-uninitialized warning in
           brcmf_cfg80211_start_ap", which is currently in net/master merge
           pending.
      
         - Dropped two x86 patches, "x86: math-emu: possible uninitialized
           variable use" and "x86: mark target address as output in 'insb'
           asm" as they do not seem to trigger for a default build, and I got
           no feedback on them. Both of these are ancient issues and seem
           harmless, I will send them again to the x86 maintainers once the
           rest is merged.
      
         - Dropped "rbd: false-postive gcc-4.9 -Wmaybe-uninitialized" based on
           feedback from Ilya Dryomov, who already has a different fix queued
           up for v4.10. The kbuild bot reports this as a warning for xtensa.
      
         - Replaced "crypto: aesni: avoid -Wmaybe-uninitialized warning" with
           a simpler patch, this one always triggers but my first solution
           would not be safe for linux-4.9 any more at this point. I'll follow
           up with the larger patch as a cleanup for 4.10.
      
         - Replaced "dib0700: fix nec repeat handling" with a better one,
           contributed by Sean Young"
      
      * -Wmaybe-uninitialized fixes:
        Kbuild: enable -Wmaybe-uninitialized warnings by default
        pcmcia: fix return value of soc_pcmcia_regulator_set
        infiniband: shut up a maybe-uninitialized warning

       "This is a fix for an unmount hang (regression) when the filesystem is

        tagged the commit prior to it in that pullreq.

         - fix for aborting deferred transactions on filesystem shutdown"

      Kbuild: enable -Wmaybe-uninitialized warnings by default · 4324cb23
      Arnd Bergmann authored
      Previously the warnings were added back at the W=1 level and above, this
      now turns them on again by default, assuming that we have addressed all
      warnings and again have a clean build for v4.10.
      
      I found a number of new warnings in linux-next already and submitted
      bugfixes for those.  Hopefully they are caught by the 0day builder in
      the future as soon as this patch is merged.

      pcmcia: fix return value of soc_pcmcia_regulator_set · 75ed2687
      Arnd Bergmann authored
      The newly introduced soc_pcmcia_regulator_set() function sometimes
      returns without setting its return code, as shown by this warning:
      
        drivers/pcmcia/soc_common.c: In function 'soc_pcmcia_regulator_set':
        drivers/pcmcia/soc_common.c:112:5: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]
      
      This changes it to propagate the regulator_disable() result instead.
      
      Fixes: ac61b600 ("pcmcia: soc_common: add support for Vcc and Vpp regulators")

      infiniband: shut up a maybe-uninitialized warning · c50e90d0
      Arnd Bergmann authored
      Some configurations produce this harmless warning when built with gcc
      -Wmaybe-uninitialized:
      
        infiniband/core/cma.c: In function 'cma_get_net_dev':
        infiniband/core/cma.c:1242:12: warning: 'src_addr_storage.sin_addr.s_addr' may be used uninitialized in this function [-Wmaybe-uninitialized]
      
      I previously reported this for the powerpc64 defconfig, but have now
      reproduced the same thing for x86 as well, using gcc-5 or higher.
      
      The code looks correct to me, and this change just rearranges it by
      making sure we alway initialize the entire address structure to make the
      warning disappear.  My first approach added an initialization at the
      time of the declaration, which Doug commented may be too costly, so I
      hope this version doesn't add overhead.

      crypto: aesni: shut up -Wmaybe-uninitialized warning · beae2c9e
      Arnd Bergmann authored
      The rfc4106 encrypy/decrypt helper functions cause an annoying
      false-positive warning in allmodconfig if we turn on
      -Wmaybe-uninitialized warnings again:
      
        arch/x86/crypto/aesni-intel_glue.c: In function ‘helper_rfc4106_decrypt’:
        include/linux/scatterlist.h:67:31: warning: ‘dst_sg_walk.sg’ may be used uninitialized in this function [-Wmaybe-uninitialized]
      
      The problem seems to be that the compiler doesn't track the state of the
      'one_entry_in_sg' variable across the kernel_fpu_begin/kernel_fpu_end
      section.
      
      This takes the easy way out by adding a bogus initialization, which
      should be harmless enough to get the patch into v4.9 so we can turn on
      this warning again by default without producing useless output.  A
      follow-up patch for v4.10 rearranges the code to make the warning go
      away.
