[PATCH v2] usb: dwc3: Remove the checks of -ENOSYS

From: Kushagra Verma
Date: Fri Jun 03 2022 - 04:22:49 EST


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.
