Since commit a1fd287780c8e91fed4957b30c757b0c93021162:
"[media] bttv-driver: fix two warnings"
cropcap.defrect.height and cropcap.bounds.height for the PAL entry are 32
resp 30 pixels too large, if a userspace app (ie xawtv) actually tries to use
the full advertised height, the resulting image is broken in ways only a
screenshot can describe.
The cause of this is the fix for this warning:
drivers/media/pci/bt8xx/bttv-driver.c:308:3: warning: initialized field overwritten [-Woverride-init]
In this chunk of the commit:
@@ -301,11 +301,10 @@ const struct bttv_tvnorm bttv_tvnorms[] = {
/* totalwidth */ 1135,
/* sqwidth */ 944,
/* vdelay */ 0x20,
- /* sheight */ 576,
- /* videostart0 */ 23)
/* bt878 (and bt848?) can capture another
line below active video. */
- .cropcap.bounds.height = (576 + 2) + 0x20 - 2,
+ /* sheight */ (576 + 2) + 0x20 - 2,
+ /* videostart0 */ 23)
},{
.v4l2_id = V4L2_STD_NTSC_M | V4L2_STD_NTSC_M_KR,
.name = "NTSC",
Which replaces the overriding of cropcap.bounds.height initialization outside
of the CROPCAP macro (which also initializes it), with passing a
different sheight value to the CROPCAP macro.
There are 2 problems with this warning fix:
1) The sheight value is used twice in the CROPCAP macro, and the old code
only changed one resulting value.
2) The old code increased the .cropcap.bounds.height value (and did not
touch the .cropcap.defrect.height value at all) by 2, where as the fixed
code increases it by 32, as the fixed code passes (576 + 2) + 0x20 - 2
to the CROPCAP macro, but the + 0x20 - 2 is already done by the macro so
now is done twice for .cropcap.bounds.height, and also is applied to
.cropcap.defrect.height where it should not be applied at all.
This patch fixes this by adding an extraheight parameter to the CROPCAP entry
and using it for the PAL entry.

The ivtv_itvc function receives a pointer to v4l2_dbg_register. When we
add const to that pointer in the s_register case we will run into a problem
here since this common function would discard const in that case. So
change this function so it receives the address and a pointer to a value.
In addition we now set the size field in the g_register function which is
where it belongs.
This will simplify the next patch where const will be added to s_register.

Previously, this has been done implicitly for video device nodes by calling
set_input() (which calls audio_input() and also modified the mute
setting).
Since input and mute setting are now untangled (as much as possible), we need to
apply the mute setting with an explicit call to audio_mute().
Also apply the mute setting when the radio device node gets opened.

Note that the current driver does not implement enumaudio (so apps cannot
tell that audio inputs are present), it does not set V4L2_CAP_AUDIO, nor
does it set audioset when calling ENUM_INPUT. And G_AUDIO doesn't set the
stereo flag either. So these g/s_audio ioctls are quite pointless and
misleading. Especially since some surveillance boards do not have audio
at all.

Just opening the radio tuner should not cause a switch to the radio tuner.
Only after calling g/s_tuner or g/s_frequency should this happen.
This prevents audio being unmuted as soon as the driver is loaded because
some process opens /dev/radioX just to see what sort of node it is, which
switches on the radio tuner and unmutes audio.
This code can be improved further by actually keeping track of who owns the
tuner and returning -EBUSY if switching tuner modes will cause problems.
But for now just fix the annoying case where on boot the radio turns on
automatically.

If no tuner is present, then disable the tuner and frequency ioctls.
We can remove a number of checks from those ioctls testing for the presence
of a tuner.
Also remove some tuner type checks (now done by the core) and fix an
error return when the prio check fails.
Finally some 'unlikely' statements are removed since those only make sense
in tightly often executed loops, otherwise they just clutter up the code.
