Hi,
loading iio_dummy results in kernel panic as the call to
iio_buffer_register in iio_dummy_probe is performed with indio_dev->buffer ==
NULL and thus the access to indio_dev->buffer->attrs results in this
oops/panic.
Thanks,
Peter
Steps to reproduce:
#modprobe iio_dummy
iio_dummy: module is from the staging directory, the quality is unknown, you
have been warned.
