ARM: perf: check that we have a platform device when reserving PMU Attempting to use a hardware counter on a platform with a supported PMU but where the platform_device (defining the interrupts) has not been registered results in a NULL pointer dereference. This patch fixes the problem by checking that we actually have a platform device registered before attempting to grab the interrupts.
