[ 44/77] media: cx18/ivtv: fix regression: remove __init from a non-init function

From: Greg Kroah-Hartman

3.8-stable review patch. If anyone has any objections, please let me know.

------------------

From: Hans Verkuil <hans.verkuil@xxxxxxxxx>

commit cfb046cb800ba306b211fbbe4ac633486e11055f upstream.

Commits 5e6e81b2890db3969527772a8350825a85c22d5c (cx18) and
2aebbf6737212265b917ed27c875c59d3037110a (ivtv) added an __init
annotation to the cx18-alsa-load and ivtv-alsa-load functions. However,
these functions are called *after* initialization by the main cx18/ivtv
driver. By that time the memory containing those functions is already
freed and your machine goes BOOM.
