Subject: V4L/DVB (7341): ivtv: rename tunerhz to tunertype
X-Git-Tag: v2.6.26-rc1~1084^2~330
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=11305d590895f22c30545ee0ff3fb434128fefb0;p=platform%2Fkernel%2Flinux-exynos.git

V4L/DVB (7341): ivtv: rename tunerhz to tunertype

There are two tuner types: those for M/N standards and those for all others.
However, M/N standards are not always 60 Hz (PAL-N/Nc are 50 Hz), so rename
the module option accordingly.
