From b253c3026c29d4231099d3cf8d984d25787793af Mon Sep 17 00:00:00 2001 From: Dexuan Cui Date: Thu, 16 Sep 2021 12:36:44 -0700 Subject: drm/hyperv: Fix double mouse pointers Hyper-V supports a hardware cursor feature. It is not used by Linux VM, but the Hyper-V host still draws a point as an extra mouse pointer, which is unwanted, especially when Xorg is running. The hyperv_fb driver uses synthvid_send_ptr() to hide the unwanted pointer. When the hyperv_drm driver was developed, the function synthvid_send_ptr() was not copied from the hyperv_fb driver. Fix the issue by adding the function into hyperv_drm.
