* master.kernel.org:/pub/scm/linux/kernel/git/mchehab/v4l-dvb: (244 commits) V4L/DVB (4210b): git-dvb: tea575x-tuner build fix V4L/DVB (4210a): git-dvb versus matroxfb V4L/DVB (4209): Added some BTTV PCI IDs for newer boards Fixes some sync issues between V4L/DVB development and GIT V4L/DVB (4206): Cx88-blackbird: always set encoder height based on tvnorm->id V4L/DVB (4205): Merge tda9887 module into tuner. V4L/DVB (4203): Explicitly set the enum values. V4L/DVB (4202): allow selecting CX2341x port mode V4L/DVB (4200): Disable bitrate_mode when encoding mpeg-1. V4L/DVB (4199): Add cx2341x-specific control array to cx2341x.c V4L/DVB (4198): Avoid newer usages of obsoleted experimental MPEGCOMP API V4L/DVB (4197): Port new MPEG API to saa7134-empress with saa6752hs V4L/DVB (4196): Port cx88-blackbird to the new MPEG API. V4L/DVB (4193): Update cx2341x fw encoding API doc. V4L/DVB (4192): Use control helpers for saa7115, cx25840, msp3400. V4L/DVB (4191): Add CX2341X MPEG encoder module. V4L/DVB (4190): Add helper functions for control processing to v4l2-common. V4L/DVB (4189): Add videodev support for VIDIOC_S/G/TRY_EXT_CTRLS. V4L/DVB (4188): Add new MPEG control/ioctl definitions to videodev2.h V4L/DVB (4186): Add support for the DNTV Live! mini DVB-T card. ...
