+Subject: [PATCH] wsi/display: Set atomic client cap in AcquireDrmDisplayEXT as
+ well.
+
+Previously we only added the atomic client cap to the drmFd passed to
+GetDrmDisplayEXT (through wsi_display_get_connector). But the drmFd
+passed to AcquireDrmDisplayEXT might be different. And that drmFd is
+what mesa will use for later operations.
+
+For example, SteamVR uses a non-master drm fd for GetDrmDisplayEXT, then
+later uses a different, leased drm fd for AcquireDrmDisplayEXT. This
+breaks things like drmModeObjectGetProperties because all atomic
+properties will be missing.
