iio: core: Fix entry not deleted when iio_register_sw_trigger_type() fails
In iio_register_sw_trigger_type(), configfs_register_default_group() is
possible to fail, but the entry add to iio_trigger_types_list is not
deleted.
This leaves wild in iio_trigger_types_list, which can cause page fault
when module is loading again. So fix this by list_del(&t->list) in error
path.
BUG: unable to handle page fault for address: fffffbfff81d7400
Call Trace:
