Zhenyu Wang 106e4b44c5 SDVO: switch bus once for i2c transfer
Before sdvo try to get edid by i2c bus, it must do switch control bus to ddc active state from sdvo only state.
However if current state has been ddc active state, redundant switch operation in our driver will cause error-
"Unable to write to SDVOCTRL_E for SDVOB Slave 0x70". The patch will do switch control bus only one time during
whole edid transmission.

It has fixed bug #19937
