  "message": "rtc: Fix hrtimer deadlock\n\nBen reported a lockup related to rtc. The lockup happens due to:\n\nCPU0                                        CPU1\n\nrtc_irq_set_state()\t\t\t    __run_hrtimer()\n  spin_lock_irqsave(\u0026rtc-\u003eirq_task_lock)    rtc_handle_legacy_irq();\n\t\t\t\t\t      spin_lock(\u0026rtc-\u003eirq_task_lock);\n  hrtimer_cancel()\n    while (callback_running);\n\nSo the running callback never finishes as it\u0027s blocked on\nrtc-\u003eirq_task_lock.\n\nUse hrtimer_try_to_cancel() instead and drop rtc-\u003eirq_task_lock while\nwaiting for the callback. Fix this for both rtc_irq_set_state() and\nrtc_irq_set_freq().\n\nCc: stable@kernel.org\nReported-by: Ben Greear \u003cgreearb@candelatech.com\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: John Stultz \u003cjohn.stultz@linaro.org\u003e\n",
