Alex DeucherandGreg Kroah-Hartman dd4c7800a9 drm/amd/display: use udelay rather than fsleep
commit 27e4dc2c05 upstream.

This function can be called from an atomic context so we can't use
fsleep().

Fixes: 01f60348d8 ("drm/amd/display: Fix 'failed to blank crtc!'")

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.
