Hans de Goede 4ceabaf790 HID: core: Do not call request_module() in async context
request_module() may not be called form async context and in some cases
hid devices may be added from an async context. One example of this
happening is under hyperv, where this was triggering a WARN_ON in
request_module():

[   11.174497]  hid_add_device+0xee/0x2b0 [hid]
[   11.174499]  mousevsc_probe+0x223/0x2eb [hid_hyperv]
[   11.174501]  vmbus_probe+0x3a/0x90
[   11.174504]  really_probe+0x229/0x420
[   11.174506]  driver_probe_device+0x115/0x130
[   11.174507]  __driver_attach_async_helper+0x87/0x90
[   11.174509]  async_run_entry_fn+0x37/0x150

This commit skips the request_module(), falling back to the old behavior
of letting userspace deal with this, in case we are called from an async
context.

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.
