Update kernel patch for kernel version 6.16.8

[Rapti]

Starting with kernel version 6.16.8, the first kernel patch could no longer be applied because all EDID_QUIRK_NON_DESKTOP were wrapped in BIT( ) in this commit.

You shouldn't need this patch on 6.16 kernel, since VivePro2 announces its own usage using EDID, and kernel is able to detect that automatically

[CertainLach]

You can check that by using edid-decode:

> edid-decode /sys/class/drm/card1-DP-3/edid

Block 1, DisplayID Extension Block:
  Version: 2.0
  Extension Count: 0
  Display Product Primary Use Case: Head-mounted Virtual Reality (VR) display

This patch was required when the kernel was not respecting this field.

I just came across this issue when trying to upgrade my kernel. So are the other patches (0002-drm-edid-parse-DRM-VESA-dsc-bpp-target_fix.patch and 0003-drm-amd-use-fixed-dsc-bits-per-pixel-from-edid.patch) also not needed anymore?

You're right, it does work without it.

Those are needed for modes 4 and 5, but you'd better use the updated version: https://lore.kernel.org/all/20251017162736.45368-1-iam@lach.pw/T/#u
(Will add it to this repo later)

The patch I linked is for 6.18-rc3, rebased for 6.17 version is in this discord thread: https://discord.com/channels/1065291958328758352/1428185501008924672
