drm/bochs: Fix the ID mismatch errordrm-fixes-2019-03-01
When running RISC-V QEMU with the Bochs device attached via PCIe the probe of the Bochs device fails with: [drm:bochs_hw_init] *ERROR* ID mismatch This was introduced by this commit: 7780eb9ce8 bochs: convert to drm_dev_register To fix the error we ensure that pci_enable_device() is called before bochs_load(). Fixes: 7780eb9ce80f ("bochs: convert to drm_dev_register") Signed-off-by: Alistair Francis <> Reported-by: David Abdurachmanov <> Link: Signed-off-by: Gerd Hoffmann <> Signed-off-by: Dave Airlie <>
