+
+This has lost in the original push for the dwc3 qcom driver.
+This is needed for ipq806x SoC as without this the usb ports
+doesn't work at all.

+Subject: phy: qualcomm: fix setting of tx_deamp_3_5db when device property
+ read fails
+
+Currently when reading of the device property for "qcom,tx-deamp_3_5db"
+fails the default is being assigned incorrectly to phy_dwc3->rx_eq. This
+looks like a copy-n-paste error and in fact should be assigning the
+default instead to phy_dwc3->tx_deamp_3_5db
+
+Addresses-Coverity: ("Copy-paste error")
+Fixes: ef19b117b834 ("phy: qualcomm: add qcom ipq806x dwc usb phy driver")
