6.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Zqiang <qiang.zhang1211@xxxxxxxxx> [ Upstream commit 77aeb1b685f9db73d276bad4bb30d48505a6fd23 ] For CONFIG_DEBUG_OBJECTS_WORK=y kernels sscs.work defined by INIT_WORK_ONSTACK() is initialized by debug_object_init_on_stack() for the debug check in __init_work() to work correctly. But this lacks the counterpart to remove the tracked object from debug objects again, which will cause a debug object warning once the stack is freed. Add the missing destroy_work_on_stack() invocation to cure that.
