Isn't this overkill?

@@ -189,6 +192,7 @@ static struct variant_data variant_qcom = {
.clkreg = MCI_CLK_ENABLE,
- .clkreg_enable = MCI_QCOM_CLK_FLOWENA,
+ .clkreg_enable = MCI_QCOM_CLK_FLOWENA |
MCI_QCOM_CLK_FEEDBACK_CLK,
.clkreg_8bit_bus_enable = MCI_QCOM_CLK_WIDEBUS_8,

Isn't this achieveing exactly the same thing without the extra fields?
You unconditionally do it at every enable anyway, don't you?
