cxd2820r: fix gpio null pointer dereference

2017-03-12T05:44:07+00:00

commit 0ffb94b6cc5df6376ab6bff5b80075641f6716f8 upstream. Setting GPIOs during probe causes null pointer deference when GPIOLIB was not selected by Kconfig. Initialize driver private field before calling set gpios. It is regressing bug since 4.9.

[media] mn88472: fix chip id check on probe

2016-12-01T14:47:22+00:00

A register used to identify chip during probe was overwritten during firmware download and due to that later probe's for warm chip were failing. Detect chip from the another register, which is located on different register bank 2.

[media] dvb: remove unused systime() function

2016-11-23T14:58:10+00:00

The systime function uses struct timespec, which we want to stop using in the kernel because it overflows in 2038. Fortunately, this use in dibx000_common is in a function that is never called, so we can just remove it. Signed-off-by: Arnd Bergmann Signed-off-by: Mauro Carvalho Chehab

[media] stv090x: use lookup tables for carrier/noise ratio

2016-11-23T14:41:49+00:00

The stv090x driver uses the lookup table for signal strength already, with this patch we use the lookup tables for carrier/noise ratio as well. This has the advantage, that values for DVB-S and DVB-S2 are now corresponding, while before they were way off. The values are now proportional to real carrier/noise ratio, while before they were corresponding to register values. So now applications are able to give the user real carrier/noise ratio. Because the output has to be within 0x0000...0xFFFF the three negative values for DVB-S2 are omitted. This is no significant loss, because reception is lost at 7.5 dB already (TT S2-1600, Cine S2), so the negative values are not really important, and also for DVB-S they don´t exist.

[media] mn88473: refactor and fix statistics

2016-11-22T18:04:30+00:00

Remove DVB-T2 BER as it does not work at all and I didn't find how to fix. Fix DVB-T and DVB-C BER. It seems to return new some realistic looking values. Use (1 << 24) base for CNR calculations to keep it in line with dvb logarithm functions. Move all statistic logic to mn88473_read_status() function. Use regmap_bulk_read() for reading multiple registers as a one go. Many more and less minor changes. Cc: Martin Blumenstingl Signed-off-by: Antti Palosaari Signed-off-by: Mauro Carvalho Chehab

Revert "[media] dvb_frontend: merge duplicate dvb_tuner_ops.release implementations"

2016-11-18T22:44:33+00:00

While this patch sounded a good idea, unfortunately, it causes bad dependencies, as drivers that would otherwise work without the DVB core will now break: ERROR: "dvb_tuner_simple_release" [drivers/media/tuners/tea5767.ko] undefined! ERROR: "dvb_tuner_simple_release" [drivers/media/tuners/tea5761.ko] undefined! ERROR: "dvb_tuner_simple_release" [drivers/media/tuners/tda827x.ko] undefined!

ERROR: "dvb_tuner_simple_release" [drivers/media/tuners/fc0011.ko] undefined! So, we have to revert it. Note: as the argument for the release ops changed from "int" to "void", we needed to change it at the revert patch, to avoid compilation issues like: drivers/media/tuners/tea5767.c:437:23: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types] .release = tea5767_release, ^~~~~~~~~~~~~~~ This reverts commit 22a613e89825ea7a3984a968463cc6d425bd8856.

[media] Kconfig: fix breakages when DVB_CORE is not selected

2016-11-18T19:59:17+00:00

On some weird randconfigs, it is possible to select DVB drivers, without having the DVB_CORE: CONFIG_DVB_AU8522=m CONFIG_DVB_AU8522_V4L=m CONFIG_DVB_TUNER_DIB0090=m This was never supposed to work, but changeset 22a613e89825 ("[media] dvb_frontend: merge duplicate dvb_tuner_ops.release implementations") caused it to be exposed: drivers/built-in.o: In function `fc0011_attach': (.text+0x1598fb): undefined reference to `dvb_tuner_simple_release' drivers/built-in.o:(.rodata+0x55e58): undefined reference to `dvb_tuner_simple_release' drivers/built-in.o:(.rodata+0x57398): undefined reference to `dvb_tuner_simple_release' Fixes: 22a613e89825 ("[media] dvb_frontend: merge duplicate dvb_tuner_ops.release implementations") Reported-by: kbuild test robot Signed-off-by: Mauro Carvalho Chehab
