[media] v4l2-tpg: Init hv_enc field with a valid value

2016-11-29T14:12:13+00:00

Zero is not a valid value for hsv_enc. Set the field to a valid initial value. This is not a problem for vivid, because it sets the field to 180 via tpg_s_hsv_enc() on the control initialization, but it might be a source of errors for other drivers that use this code.

2016-11-23T21:52:12+00:00

Fix this bug: "[BUG] process stuck when closing saa7146 [dvb_ttpci]" Release queued DMA buffers when ending streaming, so that videobuf_waiton() doesn't block forever.

[media] dvb: make DVB frontend *_ops instances "const"

2016-11-18T17:00:22+00:00

These are immutable. Making them "const" allows the compiler to move them to the "rodata" section. Note that cxd2841er_t_c_ops cannot be made "const", because cxd2841er_attach() modifies it. Ouch!

[media] tveeprom: print log messages using pr_foo()

2016-11-18T12:13:11+00:00

Unfortunately, the callers of tveeprom don't do the right thing to initialize the device. So, it produces log messages like: [ 267.533010] (null): Hauppauge model 42012, rev C186, serial# 2819348 [ 267.533012] (null): tuner model is Philips FQ1236 MK3 (idx 86, type 43) [ 267.533013] (null): TV standards NTSC(M) (eeprom 0x08) [ 267.533014] (null): audio processor is MSP3445 (idx 12) [ 267.533015] (null): has radio So, replace it to pr_foo(), as it should work fine.

[media] vivid: Fix YUV555 and YUV565 handling

2016-10-21T17:50:58+00:00

precalculate_color() had a optimization that avoided duplicated conversion for YUV formats. This optimization did not take into consideration YUV444, YUV555, YUV565 or limited range quantization. This patch keeps the optimization, but fixes the wrong handling. Signed-off-by: Ricardo Ribalda Delgado Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
