And the cancel_delayed_work_sync was already called in latter.

<title>drm/amd/amdgpu: Use IP discovery data to determine VCN enablement instead of MMSCH</title>

In the past, we use MMSCH to determine whether a VCN is enabled or not.
This is not reliable since after a FLR, MMSCH may report junk data.

It is better to use IP discovery data.

<title>drm/amdgpu/vcn: drop gfxoff control for VCN2+</title>

<id>2c1b1ac7084edf477309d27c02d9da7f79b33cec</id>
<content type='text'>
Drop disabling of gfxoff during VCN use.  This allows gfxoff
to kick in and potentially save power if the user is not using
gfx for color space conversion or scaling.

VCN1.0 had a bug which prevented it from working properly with
gfxoff, so we disabled it while using VCN.  That said, most apps
today use gfx for scaling and color space conversion rather than
overlay planes so it was generally in use anyway. This was fixed
on VCN2+, but since we mostly use gfx for color space conversion
and scaling and rapidly powering up/down gfx can negate the
advantages of gfxoff, we left gfxoff disabled. As more
applications use overlay planes for color space conversion
and scaling, this starts to be a win, so go ahead and leave
gfxoff enabled.

Note that VCN1.0 uses vcn_v1_0_idle_work_handler() and
vcn_v1_0_ring_begin_use() so they are not affected by this
patch.

This should prevent writing to memory or IO ranges possibly
already allocated for other uses after our device is removed.

v5:
Protect more places wher memcopy_to/form_io takes place
Protect IB submissions

v6: Switch to !drm_dev_enter instead of scoping entire code
with brackets.

v7:
Drop guard of HW ring commands emission protection since they
are in GART and not in MMIO.

drm-misc-next for v5.12:

UAPI Changes:
- Not necessarily one, but we document that userspace needs to force probe connectors.

Cross-subsystem Changes:
- Require FB_ATY_CT for aty on sparc64.
- video: Fix documentation, and a few compiler warnings.
- Add devicetree bindings for DP connectors.
- dma-buf: Update kernel-doc, and add might_lock for resv objects in begin/end_cpu_access.

Core Changes:
- ttm: Warn when releasing a pinned bo.
- ttm: Cleanup bo size handling.
- cma-helper: Remove prime infix, and implement mmap as GEM CMA functions.
- Split drm_prime_sg_to_page_addr_arrays into 2 functions.
- Add a new api to install irq using devm.
- Update panel kerneldoc to inline style.
- Add DP support to drm/bridge.
- Assorted small fixes to ttm, fb-helper, scheduler.
- Add atomic_commit_setup function callback.
- Automatically use the atomic gamma_set, instead of forcing drivers to declare the default atomic version.
- Allow using degamma for legacy gamma if gamma is not available.
- Clarify that primary/cursor planes are not tied to 1 crtc (depending on possible_crtcs).
- ttm: Cleanup the lru handler.

Driver Changes:
- Add pm support to ingenic.
- Assorted small fixes in radeon, via, rockchip, omap2fb, kmb, gma500, nouveau, virtio, hisilicon, ingenic, s6e63m0 panel, ast, udlfb.
- Add BOE NV110WTM-N61, ys57pss36bh5gq, Khadas TS050 panels.
- Stop using pages with drm_prime_sg_to_page_addr_arrays, and switch all callers to use ttm_sg_tt_init.
- Cleanup compiler and docbook warnings in a lot of fbdev devices.
- Use the drmm_vram_helper in hisilicon.
- Add support for BCM2711 DSI1 in vc4.
- Add support for 8-bit delta RGB panels to ingenic.
- Add documentation on how to test vkms.
- Convert vc4 to atomic helpers.
- Use degamma instead of gamma table in omap, to add support for CTM and color encoding/range properties.
- Rework omap DSI code, and merge all omapdrm modules now that the last omap panel is now a drm panel.
- More refactoring of omap dsi code.
- Enable 10/12 bpc outputs in vc4.
