Patch for Goodix 27c6:0d42 touchpads found in Inspiron 5515 laptops. After resume from suspend, one can communicate with this device just fine. We can read data from it or request a reset, but for some reason the interrupt line will not go up when new events are available. (it can correctly respond to a reset with an interrupt tho) The only way I found to wake this device up is to send anything to it after ~1.5s mark, for example a simple read request, or power mode change. In this patch, I simply delay the resume steps with msleep, this will cause the set_power request to happen after the ~1.5s barrier causing the device to resume its event interrupts. Sleep was used rather than delayed_work to make this workaround as non-invasive as possible.

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 reStructuredText 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.
