After the device is initialized, it runs ATI (calibration) during which it cannot readily respond to I2C communication. To keep the open and close callbacks from writing to the device too soon, the driver waits 100 ms before returning from probe. The vendor reports that ATI may actually take up to 250 ms to run (including margin), so increase the delay accordingly. Update the comments to clarify the reason for the delay as well.

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.
