      ir-core: fix gcc-7 warning on bool arithmetic · 0ff1117c
      Arnd Bergmann authored
      commit bd7e31bb upstream.
      
      gcc-7 suggests that an expression using a bitwise not and a bitmask
      on a 'bool' variable is better written using boolean logic:
      
      drivers/media/rc/imon.c: In function 'imon_incoming_scancode':
      drivers/media/rc/imon.c:1725:22: error: '~' on a boolean expression [-Werror=bool-operation]
          ictx->pad_mouse = ~(ictx->pad_mouse) & 0x1;
                            ^
      drivers/media/rc/imon.c:1725:22: note: did you mean to use logical not?
      
      I agree.

      disable new gcc-7.1.1 warnings for now · 83863589
      Linus Torvalds authored
      commit bd664f6b upstream.
      
      I made the mistake of upgrading my desktop to the new Fedora 26 that
      comes with gcc-7.1.1.
      
      There's nothing wrong per se that I've noticed, but I now have 1500
      lines of warnings, mostly from the new format-truncation warning
      triggering all over the tree.
      
      We use 'snprintf()' and friends in a lot of places, and often know that
      the numbers are fairly small (ie a controller index or similar), but gcc
      doesn't know that, and sees an 'int', and thinks that it could be some
      huge number.  And then complains when our buffers are not able to fit
      the name for the ten millionth controller.
      
      These warnings aren't necessarily bad per se, and we probably want to
      look through them subsystem by subsystem, but at least during the merge
      window they just mean that I can't even see if somebody is introducing
      any *real* problems when I pull.
      
      So warnings disabled for now.
