Subject: drm/amd/amdgpu: Not request init data for MS_HYPERV with vega10
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=eb85fc238970afe4a309bb307bdeecc2938ba7b2;p=linux.git

drm/amd/amdgpu: Not request init data for MS_HYPERV with vega10

MS_HYPERV with vega10 doesn't have the interface to process
request init data msg.

Check hypervisor type to not send the request for MS_HYPERV.
