Subject: [PATCH -next] media: av7110_v4l: Fix build error

drivers/media/pci/ttpci/av7110_v4l.c: In function ‘vidioc_s_frequency’:
drivers/media/pci/ttpci/av7110_v4l.c:163:11: error: SSE register return with SSE disabled
  if (freq < 16U * 168.25)
      ~~~~~^~~~~~~~~~~~~~
Get rid of float pointing math to fix this.
