commit4ad09d956fupstream. 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: <TASK> iio_register_sw_trigger_type do_one_initcall do_init_module load_module ...

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
