This is a note to let you know that I've just added the patch titled
[media] v4l2-ioctl.c: prefill tuner type for g_frequency and g/s_tuner
to the 2.6.32-longterm tree which can be found at:
http://www.kernel.org/git/?p=linux/kernel/git/longterm/longterm-queue-2.6.32.git;a=summary
The filename of the patch is:
v4l2-ioctl.c-prefill-tuner-type-for-g_frequency-and.patch
and it can be found in the queue-2.6.32 subdirectory.
If you, or anyone else, feels it should not be added to the 2.6.32 longterm
tree,
please let <sta...@kernel.org> know about it.

Subject: [media] v4l2-ioctl.c: prefill tuner type for g_frequency and g/s_tuner
From: Hans Verkuil <hans.verk...@cisco.com>
commit 227690df75382e46a4f6ea1bbc5df855a674b47f upstream.
The subdevs are supposed to receive a valid tuner type for the g_frequency
and g/s_tuner subdev ops. Some drivers do this, others don't. So prefill
this in v4l2-ioctl.c based on whether the device node from which this is
called is a radio node or not.
The spec does not require applications to fill in the type, and if they
leave it at 0 then the 'check_mode' call in tuner-core.c will return
an error and the ioctl does nothing.
