V4L/DVB (9183): S2API: Return error of the caller provides 0 commands. V4L/DVB (9182): S2API: Added support for DTV_HIERARCHY V4L/DVB (9181): S2API: Add support fot DTV_GUARD_INTERVAL and DTV_TRANSMISSION_MODE V4L/DVB (9180): S2API: Added support for DTV_CODE_RATE_HP/LP V4L/DVB (9179): S2API: frontend.h cleanup V4L/DVB (9178): cx24116: Add module parameter to return SNR as ESNO. V4L/DVB (9177): S2API: Change _8PSK / _16APSK to PSK_8 and APSK_16 V4L/DVB (9176): Add support for DvbWorld USB cards with STV0288 demodulator. V4L/DVB (9175): Remove NULL pointer in stb6000 driver. V4L/DVB (9174): Allow custom inittab for ST STV0288 demodulator. V4L/DVB (9173): S2API: Remove the hardcoded command limit during validation V4L/DVB (9172): S2API: Bugfix related to DVB-S / DVB-S2 tuning for the legacy API. V4L/DVB (9171): S2API: Stop an OOPS if illegal commands are dumped in S2API. V4L/DVB (9170): cx24116: Sanity checking to data input via S2API to the cx24116 demod. V4L/DVB (9169): uvcvideo: Support two new Bison Electronics webcams. V4L/DVB (9168): Add support for MSI TV@nywhere Plus remote V4L/DVB: v4l2-dev: remove duplicated #include ...
