Thomas Zimmermann 97c9bfe3f6 drm/aperture: Pass DRM driver structure instead of driver name
Print the name of the DRM driver when taking over fbdev devices. Makes
the output to dmesg more consistent. Note that the driver name is only
used for printing a string to the kernel log. No UAPI is affected by this
change.
