Kenny Levinsen ab5ec06a70 HID: i2c-hid: Retry address probe after delay
Some STM microcontrollers need 400µs after rising clock edge in order to
come out of their deep sleep state. This in turn means that our address
probe will fail as the device is not ready to service it.

Retry the probe once after a delay to see if the device came alive,
otherwise treat the device as missing.

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.
