[PATCH] video/tuner: add VIDEO_G_FREQUENCY and freq range to VIDIOC_G_TUNER
Jiri Benc [Sat, 7 May 2005 04:30:42 +0000 (21:30 -0700)]
This patch adds a VIDIOC_G_FREQUENCY command to tuner-core.c and sets
lowest and highest tunable frequencies in v4l2_tuner structure returned by
VIDIOC_G_TUNER command.
