Will Deacon 357b565d5d drivers/perf: arm_pmu: avoid NULL dereference when not using devicetree ... Commit c6b90653f1 ("drivers/perf: arm_pmu: make info messages more verbose") breaks booting on systems where the PMU is probed without devicetree (e.g by inspecting the MIDR of the current CPU). In this case, pdev->dev.of_node is NULL and we shouldn't try to access its ->fullname field when printing probe error messages. This patch fixes the probing code to use of_node_full_name, which safely handles NULL nodes and removes the "Error %i" part of the string, since it's not terribly useful.
