[Why] We manage interrupts for CRTCs in two places: 1. In manage_dm_interrupts(), when CRTC get enabled or disabled 2. When drm_vblank_get/put() starts or kills the vblank counter, calling into amdgpu_dm_crtc_set_vblank() The interrupts managed by these twp places should be identical. [How] Since manage_dm_interrupts() already use drm_crtc_vblank_on/off(), just move all CRTC interrupt management into amdgpu_dm_crtc_set_vblank(). This has the added benefit of disabling all CRTC and HUBP interrupts when there are no vblank requestors. Note that there is a TODO item - unchanged from when it was first introduced - to properly identify the HUBP instance from the OTG instance, rather than just assume direct mapping.

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.
