We want to add sleepable callbacks for hid_hw_raw_request() and hid_hw_output_report(), but we can not use a plain RCU for those. Prepare for a SRCU so we can extend HID-BPF. This changes a little bit how hid_bpf_device_init() behaves, as it may now fail, so there is a tiny hid-core.c change to accommodate for this.

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 reStructuredText 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.
