Subject: remove some unnecessary casts of arguments to realloc()
X-Git-Tag: 2.46.0~20^2^2~9^2~5
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=6a8512ec03ae5311241156292ba5d6bee52be7fc;p=graphviz

remove some unnecessary casts of arguments to realloc()

These parameters implicitly coerce to void* with no casting required.
