Hi Thomas,

The generic fbdev emulation names variables of type struct fb_info
both 'fbi' and 'info'. The latter seems to be more common in fbdev
code, so name fbi accordingly.
Also replace the duplicate variable in drm_fbdev_fb_destroy().

As info is already used above to find fb_helper, this check is
redundant.
Oh indeed; will fix. This change belongs to patch 8, which streamlines
the cleanup a bit.
