Mohammed Gamal 85851d9ff7 drm/hyperv: Fix device removal on Gen1 VMs ... [ Upstream commit e048834c20 ] The Hyper-V DRM driver tries to free MMIO region on removing the device regardless of VM type, while Gen1 VMs don't use MMIO and hence causing the kernel to crash on a NULL pointer dereference. Fix this by making deallocating MMIO only on Gen2 machines and implement removal for Gen1 Fixes: 76c56a5aff ("drm/hyperv: Add DRM driver for hyperv synthetic video device") Signed-off-by: Mohammed Gamal <mgamal@redhat.com> Reviewed-by: Deepak Rawat <drawat.floss@gmail.com> Signed-off-by: Deepak Rawat <drawat.floss@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211119112900.300537-1-mgamal@redhat.com Signed-off-by: Sasha Levin <sashal@kernel.org>		2021-12-01 09:04:51 +01:00
