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."}], "lastModified": "2026-02-06T17:16:22.930", "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67"}
