2013-06-17[media] v4l2: remove g_chip_ident from bridge drivers where it is easy to do soHans Verkuil
VIDIOC_DBG_G_CHIP_IDENT has been replaced by VIDIOC_DBG_G_CHIP_INFO. Remove g_chip_ident support from bridge drivers since it is no longer needed. This patch takes care of all the trivial cases.

2013-03-25[media] au0828: improve firmware loading & lockingHans Verkuil
- open/close/read and poll need to take the core lock as well. - when the tuner goes to sleep we should set std_set_in_tuner_core to 0 since the tuner loses the firmware at that time. - initialize the tuner if std_set_in_tuner_core == 0 whenever: 1) g/s_tuner, s_std or s_frequency is called 2) read or poll is called 3) streamon is called Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Reviewed-by: Devin Heitmueller <dheitmueller@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

The driver crashed when the device was disconnected while an application still had a device node open. Fixed by using the release() callback of struct v4l2_device.

- V4L2_CAP_AUDIO was set, but enumaudio was not implemented. - audioset was never filled by enum_input - ctrl_ainput was never updated when switching the video input - g_audio was broken due to faulty logic: g_audio should set the index, it doesn't receive it from the user.

- define an initial frequency - return an error if g_frequency is called for an invalid tuner index - get the clamped frequency value after setting it: i.e. the tuner driver may clamp the given frequency to a valid frequency range and ctrl_freq should get that actual clamped frequency. - remove obsolete tuner type checks (done by the core).

This ioctl is defined as IOW, so pass the argument by value instead of by reference. I could have chosen to add const instead, but this is 1) easier to handle in drivers and 2) consistent with the s_std subdev operation.
