  This card has the following ICs: Hybrid tuner TDA18271, CX23888 PCIe bridge/demodulator/decoder (and DVB-T demodulator AF9013S, which is not within the scope of this patch). It has the following inputs: Tuner, S-Video, Composite (shared with the luma input of S-Video) and Audio L/R RCA. VID:PID is 1461:e139. When the patch is applied and the cx23885 kernel module is built and loaded, the following dmesg can be seen:

The card has to be defined in cx23885-cards.c (firmware also has to be loaded) and cx23885.h. Moreover, audio routing is configured in cx23885-video.c. Analog tuning, composite, s-video and stereo audio inputs have been successfully tested with PAL B/G.
