Michael Kelley c40cd24bfb drm/hyperv: Fix address space leak when Hyper-V DRM device is removed ... [ Upstream commit aed709355fd05ef747e1af24a1d5d78cd7feb81e ] When a Hyper-V DRM device is probed, the driver allocates MMIO space for the vram, and maps it cacheable. If the device removed, or in the error path for device probing, the MMIO space is released but no unmap is done. Consequently the kernel address space for the mapping is leaked. Fix this by adding iounmap() calls in the device removal path, and in the error path during device probing.
