the\nembedded struct device in pdev has already been initialized by\ndevice_initialize(), but the failure path only reports the error and\nreturns without dropping the device reference for the current platform\ndevice:\n\n  sm501_register_device()\n    -> platform_device_register(pdev)\n       -> device_initialize(&pdev->dev)\n       -> setup_pdev_dma_masks(pdev)\n       -> platform_device_add(pdev)\n\nThis leads to a reference leak when platform_device_register() fails.\nFix this by calling platform_device_put() before returning the error.\n\nThe issue was identified by a static analysis tool I developed and\nconfirmed by manual
