[Why&How] As reported on https://gitlab.freedesktop.org/drm/amd/-/issues/3936, SMU hang can occur if the interrupts are not enabled appropriately, causing a vblank timeout. This patch reverts commit5009628d85("drm/amd/display: Remove unnecessary amdgpu_irq_get/put"), but only for RX6xxx & RX7700 GPUs, on which the issue was observed. This will re-enable interrupts regardless of whether the user space needed it or not.

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.
