lib/zlib_inflate/inftrees.c: fix potential buffer overflow
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
