Subject: [PATCH] usb: dwc3: Remove the checks of -ENOSYS
Commit 57303488cd37d ("usb: dwc3: adapt dwc3 core to use Generic PHY
Framework") added if statements that check 'ret == -ENOSYS || ret ==
-ENODEV', but the function phy_get() which is called by devm_phy_get()
returns the phy driver or -ENODEV if the phy driver was not found. So,
remove the check of -ENOSYS in the if statements.
