* [media] rtl28xxu: fix buffer overflow when probing Rafael Micro r820t tunerGianluca Gennari2013-06-17
| | | | | | | | | | | As suggested by Antti, this patch replaces: https://patchwork.kernel.org/patch/2649861/ The buffer overflow is fixed by reading only the r820t ID register.

* [media] it913x: rename its tuner driver to tuner_it913xMauro Carvalho Chehab2013-04-16
| | | | | | | | | | | | | | | | | | | | There are three drivers with *it913x name on it, and they all belong to the same device: a tuner, at it913x.c; a frontend: it913x-fe.c; a bridge: it913x.c, renamed to dvb_usb_it913x by the building system. This is confusing. Even more confusing are the two .c files with the same name under different directories, with different contents and different functions. So, prepend the tuner one. This also breaks the out-of-tree compilation system.

| | | | | | | | | | | Loading the cypress firmware is not dvb specific and should be common functionality. Move the source to media/common and make it a standalone module. As a result we can remove the dependency on dvb-usb in go7007, which has nothing to do with dvb.

* [media] it913x: fix pid filterAntti Palosaari2013-03-23
| | | | | | | | | | | | | | I just made commit: "dvb_usb_v2: rework USB streaming logic" that breaks that driver PID filter. it913x driver checks use of PID filter directly from DVB USB v2 core internal variable "adap->pid_filtering" and stores it to own state. Calling order of .pid_filter_ctrl() and .pid_filter() was changed and due to that state was updated too late. Update state earlier. TODO: checking PID filter usage from DVB USB v2 is not very good idea as PID filter callbacks are called only when PID filter is enabled.
