[ Upstream commit a7de6eac6f6f73d48d97a6c93032107775f4593b ]
The driver uses v4l2_get_link_freq() helper to obtain the link frequency using the LINK_FREQ but also the PIXEL_RATE control. The divisor for the pixel rate derived link frequency was wrong, missing the bus uses double data rate. Fix this.
