Subject: drm/vmwgfx: Sync legacy multisampling device capability
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 0652ff336386322a866df314fee193d5e035b6c8
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
In favor of SM4.1 multisampling capability, virtual device deprecated
old multisampling device capability. Mark legacy multisampling device
capability as dead. Rename the function that masks legacy multisample
capability to reflect that now it is masking a deprecated feature.
