In C89, "void *" is automatically promoted to any pointer type. Casting the result of malloc/calloc to the type of the LHS variable is therefore unneeded. Most of this patch was built using this Coccinelle patch: @@ type T; @@ - (T *) (\(lua_touserdata\|malloc\|calloc\|SSL_get_app_data\|hlua_checkudata\|lua_newuserdata\)(...)) @@ type T; T *x; void *data; @@ x = - (T *) data @@ type T; T *x; T *data; @@ x = - (T *) data Unfortunately, either Coccinelle or I is too limited to detect situation where a complex RHS expression is of type "void *" and therefore casting is not needed. Those cases were manually examined and corrected.
