2014-11-21[media] rtl28xxu: add support for Panasonic MN88473 slave demodAntti Palosaari
There is RTL2832P devices having extra MN88473 demodulator. This patch add support for such configuration. Logically MN88473 slave demodulator is connected to RTL2832 master demodulator, both I2C bus and TS input. RTL2832 is integrated to RTL2832U and RTL2832P chips. Chip version RTL2832P has extra TS interface for connecting slave demodulator. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

2014-11-03[media] cx231xx: Improve the log messageMauro Carvalho Chehab
Unfortunately, on devices that have multiple interfaces, udev->dev points to the parent device (usb) instead of the cx231xx specific one. Due to that the logs don't look too nice, as they'll print messages as if they were produced by USB core: usb-1-2: New device Conexant Corporation Polaris AV Capturb @ 480 Mbps (1554:5010) with 7 interfaces Instead of using the name of the parent device, let's use the name of the first cx231xx interface for all cx231xx sub-modules. With this path, the logs will be nicer: cx231xx 1-2:1.1: New device Conexant Corporation Polaris AV Capturb @ 480 Mbps (1554:5010) with 7 interfaces Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

2014-11-03[media] cx231xx: Cleanup printk at the driverMauro Carvalho Chehab
There are lots of debug printks printed with pr_info. Also, the printk's data are not too coherent: - there are duplicated driver name at the print format; - function name format string differs from function to function; - long strings broken into multiple lines; - some printks just produce ugly reports, being almost useless as-is. Do a cleanup on that. Still, there are much to be done in order to do a better printk job on this driver, but, at least it will now be a way less verbose, if debug printks are disabled, and some logs might actually be useful.

2014-11-03[media] cxusb: TS mode setting for TT CT2-4400Olli Salonen
There is a new version of the TechnoTrend CT2-4400 USB tuner. The difference is the demodulator that is used (Si2168-B40 instead of -A30). For TT CT2-4400v2 a TS stream related parameter needs to be set, otherwise the stream becomes corrupted. The Windows driver for both CT2-4400 and CT2-4400v2 sets this as well.

This patches fixes an ancient bug in the dvb_usb_af9005 driver, which has been reported at least in the following threads: https://lkml.org/lkml/2009/2/4/350 https://lkml.org/lkml/2014/9/18/558 If the driver is compiled in without any IR support (neither DVB_USB_AF9005_REMOTE nor custom symbols), the symbol_request calls in af9005_usb_module_init() return pointers != NULL although the IR symbols are not available. This leads to the following oops: ...

Until anyone who still has this old hardware steps up an does the conversion, fix it by not calling the symbol_request calls if the driver is compiled in without the default IR symbols (CONFIG_DVB_USB_AF9005_REMOTE). Due to the IR related pointers beeing NULL by default, IR support will then be disabled. The downside of this solution is, that it will no longer be possible to compile custom IR symbols (not using CONFIG_DVB_USB_AF9005_REMOTE) in. Please note that this patch has NOT been tested with all possible cases. I don't have the hardware and could only verify that it fixes the reported bug.
