Subject: [PATCH] phy: rockchip: usbdp: fix uninitialized variable
|
|
|
|
The ret variable may not be initialized in rk_udphy_usb3_phy_init(), if
|
|
the PHY is not using USB3 mode.
|
|
|
|
Since the DisplayPort part is handled separately and the PHY does not
|
|
support USB2 (which is routed to another PHY on Rockchip RK3588), the
|
|
right exit code for this case is 0. Thus let's initialize the variable
|
|
accordingly.
