For the first time during\niio_device_unregister() then later on inside\niio_device_unregister_eventset() and iio_buffers_free_sysfs_and_mask().\nDouble free leads to kernel panic.\n\nFix this by not touching ioctl handlers list directly but rather\nletting code responsible for registration call the matching cleanup\nroutine itself."

Por primera vez durante iio_device_unregister() y luego dentro de iio_device_unregister_eventset() y iio_buffers_free_sysfs_and_mask(). La doble liberaci\u00f3n conduce al p\u00e1nico en el kernel. Para solucionar este problema, no toque directamente la lista de controladores ioctl, sino que permita que el c\u00f3digo responsable del registro llame a la rutina de limpieza coincidente."
