Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux

Connecting master to an output port when GTH driver module is not loaded
triggers a NULL dereference:
> RIP: 0010:intel_th_set_output+0x35/0x70 [intel_th]
> Call Trace:
> ? sth_stm_link+0x12/0x20 [intel_th_sth]
> stm_source_link_store+0x164/0x270 [stm_core]
> dev_attr_store+0x17/0x30
> sysfs_kf_write+0x3e/0x50
> kernfs_fop_write+0xda/0x1b0
> __vfs_write+0x1b/0x40

> __x64_sys_write+0x1a/0x20
> do_syscall_64+0x57/0x1d0
> entry_SYSCALL_64_after_hwframe+0x44/0xa9
Make sure the module in question is loaded and return an error if not.

README
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.
