drivers: psci: annotate timer on stack to silence odebug messages
When DEBUG_OBJECTS config is enabled, we get the below odebug warnings: ODEBUG: object is on stack, but not annotated WARNING: CPU: 3 PID: 1304 at kernel/lib/debugobjects.c:300 __debug_object_init+0x1f0/0x458 CPU: 3 PID: 1304 Comm: psci_suspend_te Tainted: G W 4.9.0-06564-gf80f3f199260 #284 task: ffffe9e1b55a1600 task.stack: ffffe9e1b51c0000 PC is at __debug_object_init+0x1f0/0x458 LR is at __debug_object_init+0x1ec/0x458 Call trace: __debug_object_init+0x1f0/0x458 debug_object_activate+0x150/0x260 mod_timer+0xb4/0x4c0 suspend_test_thread+0x1cc/0x3c0 kthread+0x110/0x140 ret_from_fork+0x10/0x40 This patch annotates the timer on the stack using setup_timer_on_stack function to remove the above warnings.
