However, since the\ncontroller was registered via a devm function, the device core will\nautomatically call spi_controller_put() again when the probe fails.\nThis results in a double-free of the spi_controller structure.\n\nFix this by switching to devm_spi_alloc_host() and removing the\nmanual spi_controller_put() call."
