[GIT PULL FOR v3.8] Regression fix: cx18/ivtv: remove __init from a non-init function.

[Hans Verkuil]

Mauro,

Please fast-track this for 3.8. Yesterday I discovered that commits made earlier
for 3.8 kill ivtv and cx18 (as in: unable to boot, instant crash) since a
function was made __init that was actually called *after* initialization.

We are already at rc6 and this *must* make it for 3.8. Without this patch
anyone with a cx18/ivtv will crash immediately as soon as they upgrade to 3.8.

Regards,

	Hans

Hmm... the patch seems to be broken/incomplete:

It turned out that the cx18/ivtv-alsa-pcm.h header had an __init annotation,
although the corresponding function in the c source didn't. And
CONFIG_DEBUG_SECTION_MISMATCH was turned off, so I didn't see the full warning
message (now corrected). The fact that __init wasn't present in the C source
is the reason why the fix worked.

I'll post a new pull request fixing the headers as well.

	Hans

[GIT PULL FOR v3.8] Regression fix: cx18/ivtv: remove __init from a non-init function.

[Hans Verkuil]

Mauro,

Please fast-track this for 3.8. Two days ago I discovered that commits made
earlier for 3.8 kill ivtv and cx18 (as in: unable to boot, instant crash) since
a function was made __init that was actually called after initialization.

We are already at rc7 and this should make it for 3.8 if at all possible.
Without this patch anyone with a cx18/ivtv will crash immediately as soon
as they upgrade to 3.8.

This second version of the pull request also corrects two headers where __init
was present for the snd_cx18/ivtv_pcm_create function. The function in the C
source didn't have that annotation, so the first version of my fix worked fine,
it just generated false warnings which are now fixed as well.

Regards,

      Hans
