smatch says:

  WARNING: please, no spaces at the start of a line
  #30: FILE: lib/zlib_inflate/inftrees.c:112:
  +    for (min = 1; min < MAXBITS; min++)$

  total: 0 errors, 1 warnings, 8 lines checked

NOTE: For some of the reported defects, checkpatch may be able to
      mechanically convert to the typical style using --fix or --fix-inplace.

./patches/zlib-inflate-fix-potential-buffer-overflow.patch has style problems, please review.

NOTE: If any of the errors are false positives, please report
      them to the maintainer, see CHECKPATCH in MAINTAINERS.

Please run checkpatch prior to sending patches
