[Why] Today a parameter is passed to dmub_srv_send_gpint_command which specifies the max amount of time to wait for the command to be acked. This parameter instead specifies the number of times to check if the command was acked. We wish to add a lower bound to the timeout, which can be accomplished by using a delay or a timestamp. It has been decided to use udelay instead of a timestamp simply because we don't want to expose a high precision counter if it doesn't yield large benefits. [How] Add udelay(1) between each for loop iteration.

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.
