Subject: liblzma: Update assert in vli_ceil4().
X-Git-Tag: v5.2.13~73
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=519896fc94ed2a1518c9083db06575f1813e94ce;p=thirdparty%2Fxz.git

liblzma: Update assert in vli_ceil4().

The argument to vli_ceil4() should always guarantee the return value
is also a valid lzma_vli. Thus the highest three valid lzma_vli values
are invalid arguments. All uses of the function ensure this so the
assert is updated to match this.
