MAINTAINERS & files: Canonize the e-mails I use at files

2018-05-04T10:21:06+00:00

From now on, I'll start using my @kernel.org as my development e-mail. As such, let's remove the entries that point to the old mchehab@s-opensource.com at MAINTAINERS file. For the files written with a copyright with mchehab@s-opensource, let's keep Samsung on their names, using mchehab+samsung@kernel.org, in order to keep pointing to my employer, with sponsors the work. For the files written before I join Samsung (on July, 4 2013), let's just use mchehab@kernel.org. For bug reports, we can simply point to just kernel.org, as this will reach my mchehab+samsung inbox anyway.

media: cx231xx: Increase USB bridge bandwidth

2018-04-04T10:27:28+00:00

The cx231xx USB bridge has issue streaming QAM256 DVB-C channels. QAM64 channels were fine, but QAM256 channels produced corrupted transport streams. cx231xx alt mode 4 does not provide enough bandwidth to acommodate QAM256 DVB-C channels, most likely DVB-T2 channels would break up as well. Alt mode 5 increases bridge bandwidth to 90Mbps, and fixes QAM256 DVB-C streaming. Signed-off-by: Brad Love Signed-off-by: Mauro Carvalho Chehab

media: dvb-usb-v2: fix a missing dependency of I2C_MUX

2018-03-23T12:44:37+00:00

Now that af9015 requires I2C_MUX, all drivers that select it should also depend on it. drivers/media/dvb-frontends/af9013.o: In function `af9013_remove': >> drivers/media/dvb-frontends/af9013.c:1560: undefined reference to `i2c_mux_del_adapters' drivers/media/dvb-frontends/af9013.o: In function `af9013_probe': >> drivers/media/dvb-frontends/af9013.c:1488: undefined reference to `i2c_mux_alloc' >> drivers/media/dvb-frontends/af9013.c:1495: undefined reference to `i2c_mux_add_adapter' drivers/media/dvb-frontends/af9013.c:1544: undefined reference to `i2c_mux_del_adapters' Reported-by: kbuild test robot Signed-off-by: Mauro Carvalho Chehab

media: uvc: to the right check at uvc_ioctl_enum_framesizes()

2018-03-23T12:37:27+00:00

While the logic there is correct, it tricks both humans and machines, a the check if "i" var is not zero is actually to validate if the "frames" var was initialized when the loop ran for the first time. That produces the following warning: drivers/media/usb/uvc/uvc_v4l2.c:1192 uvc_ioctl_enum_framesizes() error: potentially dereferencing uninitialized 'frame'. Change the logic to do the right test instead. Signed-off-by: Mauro Carvalho Chehab

media: em28xx-input: improve error handling code

2018-03-23T11:33:22+00:00

The current I2C error handling logic makes static analyzers confused: drivers/media/usb/em28xx/em28xx-input.c:96 em28xx_get_key_terratec() error: uninitialized symbol 'b'. Change it to match the coding style we're using elsewhere. Signed-off-by: Mauro Carvalho Chehab
