…eaks When running device-introspect-test, a memory leak occurred in the digic_timer_init function, so use ptimer_free() in the finalize function to avoid it. ASAN shows memory leak stack: Indirect leak of 288 byte(s) in 3 object(s) allocated from: #0 0xffffab97e1f0 in __interceptor_calloc (/lib64/libasan.so.5+0xee1f0) #1 0xffffab256800 in g_malloc0 (/lib64/libglib-2.0.so.0+0x56800) #2 0xaaabf555db78 in ptimer_init /qemu/hw/core/ptimer.c:432 qemu#3 0xaaabf5b04084 in digic_timer_init /qemu/hw/timer/digic-timer.c:142 qemu#4 0xaaabf6339f6c in object_initialize_with_type /qemu/qom/object.c:515 qemu#5 0xaaabf633ca04 in object_initialize_child_with_propsv /qemu/qom/object.c:564 qemu#6 0xaaabf633cc08 in object_initialize_child_with_props /qemu/qom/object.c:547 qemu#7 0xaaabf5b40e84 in digic_init /qemu/hw/arm/digic.c:46 qemu#8 0xaaabf6339f6c in object_initialize_with_type /qemu/qom/object.c:515 qemu#9 0xaaabf633a1e0 in object_new_with_type /qemu/qom/object.c:729 qemu#10 0xaaabf6375e40 in qmp_device_list_properties /qemu/qom/qom-qmp-cmds.c:153 qemu#11 0xaaabf653d8ec in qmp_marshal_device_list_properties /qemu/qapi/qapi-commands-qdev.c:59 qemu#12 0xaaabf6587d08 in do_qmp_dispatch_bh /qemu/qapi/qmp-dispatch.c:110 Reported-by: Euler Robot <euler.robot@huawei.com> Signed-off-by: Gan Qixin <ganqixin@huawei.com> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
