drm/i915: Multiply the refresh by 1000 in TV mode validatiion
As of 559ee21d261a54c42594ef9405d27e9008eedf44 the actual refresh rate is returned by the function of drm_mode_vrefresh, so multiply the refresh rate by 1000 in TV mode validation. At the same time the error is expanded from 10 to 1000. Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Eric Anholt <eric@anholt.net>
