[media] dvbdev: split dvb_unregister_device()

2016-11-18T17:02:39+00:00

dvb_unregister_device() has a major problem: it combines unregistering with memory disposal. Sometimes, it is necessary to unregister a device, but no memory can be freed yet, because a process still has a (stale) file handle. Therefore, we need to split dvb_unregister_device(). This will allow sanitizing a few callers. With my new design, dvb_unregister_device() appears misnamed, but to reduce patch noise, I'm not renaming it just yet.

[media] dvb-core: use pr_foo() instead of printk()

2016-10-21T10:41:19+00:00

The dvb-core directly calls printk() without using the modern printk macros, or using the proper printk levels. Change it to use pr_foo(). Signed-off-by: Mauro Carvalho Chehab

[media] media/dvb-core: forward media_create_pad_links() return value

2016-05-07T13:56:55+00:00

Instead of always return -ENOMEM, return the real error that should come from media_create_pad_link(). Signed-off-by: Max Kellermann Signed-off-by: Mauro Carvalho Chehab

[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. Signed-off-by: Olli Salonen Signed-off-by: Mauro Carvalho Chehab

[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. Signed-off-by: Xiubo Li Signed-off-by: Mauro Carvalho Chehab

[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. Signed-off-by: Xiubo Li Signed-off-by: Mauro Carvalho Chehab

[media] dvbdev: remove useless parentheses after return

2016-02-01T12:24:44+00:00

The parentheses are not required after return, and just remove it. Signed-off-by: Xiubo Li Signed-off-by: Mauro Carvalho Chehab

[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. Signed-off-by: Mauro Carvalho Chehab

[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. Signed-off-by: Mauro Carvalho Chehab

[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. Signed-off-by: Mauro Carvalho Chehab
