[PATCH] video: rockchip: Set return code

[Andrew Goodbody]

In rk_edp_start_aux_transaction the check for "AUX CH command reply
received" returns ret as the error code but it has not been assigned a
value so this could lead to the calling code silently ignoring the
error. Instead return -EIO.

This issue was found by Smatch.
