Re: [V3] drm/loongson: Error out if no VRAM detected

Hi, I have already merged this patch, no further action is required.

[PATCH V3] drm/loongson: Error out if no VRAM detected

If there is no VRAM (it can be true if there is a discreted card, this is probably a hardware configuration issue in BIOS but it is observed in GDC-1401 laptop, L71 laptop and some Loongson-3C5000L based servers), we get such an error and Xorg fails to start: [ 136.401131] loongson :00:06.1:
