[PATCHv2] virtio_mmio: fix devm cleanup
Recent rework of the virtio_mmio probe/remove paths balanced a devm_ioremap() with an iounmap() rather than its devm variant. This ends up corrupting the devm datastructures, and results in the following boot-time splat on arm64 under QEMU 2.9.0: [ 3.450397] ------------[ cut here ]------------ [ 3.453822] Trying to vfree() nonexistent vm area (00000000c05b4844) [ 3.460534] WARNING: CPU:
