[ Upstream commit879c001afb] A device_node reference obtained from the device tree is not released on all error paths in the arm_scpi probe path. Specifically, a node returned by of_parse_phandle() could be leaked when the probe failed after the node was acquired. The probe function returns early and the shmem reference is not released. Use __free(device_node) scope-based cleanup to automatically release the reference when the variable goes out of scope.
