[media] dvb-core: fix return code checking for devices with CA

2016-03-03T17:33:33+00:00

The test for the return code was mistakenly inverted. This caused DVB
devices with CA module to fail on modprobe.

Tested with TechnoTrend CT2-4650 CI USB tuner.

[media] dvbdev: the space is required after ','

2016-02-01T12:25:59+00:00

The space is missing after ',', and this will be introduce much
noise when checking new patch around them.

[media] dvbdev: replace kcalloc with kzalloc

2016-02-01T12:25:16+00:00

Since the number of elements equals to 1, so just use kzalloc to
simplify the code and make it more readable.

[media] tuner.h: rename TUNER_PAD_IF_OUTPUT to TUNER_PAD_OUTPUT

2016-02-01T09:19:08+00:00

The output of a tuner is not only IF frequencies. They may also
output audio on some of its pins, and may even be a zero-IF tuner,
with outputs a baseband. So, rename the PAD name to make it
clearer and add a proper documentation about that at tuner.h.

No functional changes.

[media] dvbdev: create links on devices with multiple frontends

2016-01-11T14:19:26+00:00

Devices like mxl111sf-based WinTV Aero-m have multiple
frontends, all linked on the same demod. Currently, the
dvb_create_graph() function is not smart enough to create
multiple links. Fix it.

[media] dvbdev: Add RF connector if needed

2016-01-11T14:19:25+00:00

Several pure digital TV devices have a frontend with the tuner
integrated on it. Add the RF connector when dvb_create_media_graph()
is called on such devices.

Tested with siano and dvb_usb_mxl111sf drivers.

[media] dvbdev: remove two dead functions if !CONFIG_MEDIA_CONTROLLER_DVB

2016-01-11T14:19:25+00:00

Those functions are used only if CONFIG_MEDIA_CONTROLLER_DVB.
Without that, if !CONFIG_MEDIA_CONTROLLER_DVB, it would produce
two warnings:

drivers/media/dvb-core/dvbdev.c:219:12: warning: 'dvb_create_tsout_entity' defined but not used [-Wunused-function]
 static int dvb_create_tsout_entity(struct dvb_device *dvbdev,

[media] media framework: rename pads init function to media_entity_pads_init()

2016-01-11T14:19:03+00:00

With the MC next gen rework, what's left for media_entity_init()
is to just initialize the PADs. However, certain devices, like
a FLASH led/light doesn't have any input or output PAD.

So, there's no reason why calling media_entity_init() would be
mandatory. Also, despite its name, what this function actually
does is to initialize the PADs data. So, rename it to
media_entity_pads_init() in order to reflect that.

The media entity actual init happens during entity register,
at media_device_register_entity(). We should move init of
num_links and num_backlinks to it.

[media] media_entity: remove gfp_flags argument

2016-01-11T14:19:02+00:00

We should not be creating device nodes at IRQ contexts. So,
the only flags we'll be using will be GFP_KERNEL. Let's
remove the gfp_flags, in order to make the interface simpler.

If we ever need it, it would be easy to revert those changes.

While here, remove an extra blank line.
