Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/v4l-dvb
* 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/v4l-dvb: V4L/DVB (6028): Turn an unnecessary mdelay() into msleep(). V4L/DVB (6027): Get rid of an ill-behaved msleep in i2c write V4L/DVB (6026): Avoid powering up the camera on resume V4L/DVB (6016): get_dvb_firmware: update script for new location of tda10046 firmware V4L/DVB (5991): dvb-pll: Set minimum and maximum frequency properly V4L/DVB (5969): ivtv: report ivtv version in status log V4L/DVB (5967): ivtv: fix VIDIOC_S_FBUF:new OSD values where never set V4L/DVB (5968): videodev2.h: remove superfluous FBUF GLOBAL_INV_ALPHA support
