+Subject: [PATCH] thorvg: fix build with gcc-15
+
+* add missing include to fix:
+  src/libs/thorvg/thorvg.h:357:20: error: 'uint8_t' has not been declared
+  357 |     Result opacity(uint8_t o) noexcept;
+      |                    ^~~~~~~
+
+* not needed with latest master where it was resolved differently in
+  fc5c15638 feat(thorvg): use LVGL's malloc/realloc/zalloc/free (#7772)
+  which includes stdlib/lv_string.h which includes misc/lv_types.h which
+  includes stdint
+
+Upstream-Status: Pending [not needed with latest master where it was resolved differently in fc5c15638 feat(thorvg): use LVGL's malloc/realloc/zalloc/free (#7772)]
