Adding printouts to the i2c_hid_probe() function shows that it takes
quite some time. It used to take about 70 ms, but after commit
eef4016243 ("HID: i2c-hid: Always sleep 60ms after I2C_HID_PWR_ON
commands") it takes about 190 ms. This is not tons of time but it's
not trivial. Because we haven't yet specified that we'd prefer
asynchronous probe for this driver then, if the driver is builtin to
the kernel, we'll wait for this driver to finish before we start
probes for more drivers. Let's set the flag to enable asynchronous
for this driver so that other drivers aren't blocked from probing
until we finish.
Since this driver can be configured as a module and modules are
always asynchronously probed this is quite a safe change and will
benefit anyone who has a reason to build this driver into the kernel
instead of using it as a 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.
