Phil Chang a855d12979 hrtimer: Prevent queuing of hrtimer without a function callback ... [ Upstream commit 5a830bbce3af16833fe0092dec47b6dd30279825 ] The hrtimer function callback must not be NULL. It has to be specified by the call side but it is not validated by the hrtimer code. When a hrtimer is queued without a function callback, the kernel crashes with a null pointer dereference when trying to execute the callback in __run_hrtimer(). Introduce a validation before queuing the hrtimer in hrtimer_start_range_ns().
