+Subject: [PATCH] cdo: Fix incompatible-pointer-types in
+ cdoseq_load_cdo_from_buffer
+
+GCC 14 promotes -Wincompatible-pointer-types to a hard error, so the
+build fails with:
+
+  utils/src/cdo-load.c:140:14: error: assignment to 'char *' from incompatible pointer type 'uint32_t *' {aka 'unsigned int *'} [-Wincompatible-pointer-types]
+    140 |         data = raw->data;
+        |              ^
+  make: *** [Makefile:81: build/obj/cdo-load.o] Error 1
+
+The function parameter data is char *, but raw->data (struct CdoRawInfo)
+is uint32_t *. The sibling function cdoseq_load_cdo avoids this because
+its local data is void *, which accepts any pointer without a cast.
+
+Add an explicit (char *) cast.
