Subject: remove unnecessary allocation function result casts in scan.l
X-Git-Tag: 2.47.3~5^2~2

remove unnecessary allocation function result casts in scan.l

This input is only used to create a lexer in C. In C, void pointers (as is the
result of realloc) implicitly coerce to all other pointer types.
