[Why] During gpu-reset, we toggle vblank irq by calling dc_interrupt_set() instead of amdgpu_irq_get/put() because we don't want to change the irq source's refcount. However, we see the warning when vblank irq is enabled by dc_interrupt_set() during gpu-reset but disabled by amdgpu_irq_put() after gpu-reset. [How] Only in dm_gpureset_toggle_interrupts() we toggle vblank interrupts by calling dc_interrupt_set(). Apart from this we call dm_set_vblank() which uses amdgpu_irq_get/put() to operate vblank irq.

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.
