Hmm, that code is a remnant from older revisions of this driver. Unfortunately,
when I compiled this driver before creating my pull request I forgot to turn on
the CONFIG_VIDEO_ADV_DEBUG option and so I never saw it.

Also fixed the g_register function: it never returned a register
value in the original code.
