      dix: Hush an almost certainly bogus warning · 6f0903dd

                            ^~
      
      This one is truly special. Even though both ox and oy are set and read
      along the same paths, only oy is marked for this warning! Initializing
      just oy = 0.0 fixes it entirely, but let's not make a weird thing
      weirder.

      etc. It's initialized if (extents), and then only read if (extents),
      but gcc doesn't seem to figure that out. Whatever, bzero it to be
      explicit.

      xkb: Silence some compiler warnings · 83913de2

      Of the form:
      
      ../xkb/XKBGAlloc.c: In function ‘SrvXkbAddGeomKeyAlias’:
      ../xkb/XKBGAlloc.c:591:13: warning: ‘strncpy’ specified bound 4 equals destination size [-Wstringop-truncation]

                   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      
      This is intentional; the code that reads from these fields never reads
      more than 4 bytes anyway. Rephrase things in terms of memcpy so that's
      clear. Obviously this is awful but in XKB awful is par.

      The thing it's warning about is intentional, the surrounding code does
      its own nul-termination. Make that obvious by using memcpy instead.

      snprintf doesn't terminate the string if it truncates, so things like
      this are lurking crashers:

      That's pretty nitpicky of you, gcc, but at least it's easy to fix.

      modesetting: Actually get framebuffer ID · 99f9b077
      Daniel Stone authored
      
      
      We would fail to get the FB ID if it wasn't already imported, since we
      were checking to see if the pointer was NULL (it never was) rather than
      if the content of the pointer was 0.

      For old clients using the fd_from_pixmap entrypoint, make sure we set
      stride and size correctly.
      
      Noticed by inspection.

      modesetting: Don't reuse iterator in nested loop · 78574a66
      Daniel Stone authored
      
      
      drmmode_crtc_set_mode has a loop nested inside another loop, where both
      of them were using 'i' as the loop iterator. Rename it to avoid an
      infinite loop.
