   4 Subject: [PATCH 15/29] usb: fotg210-udc: fix error return code in
   5  fotg210_udc_probe()
   6
   7 After commit  5f217ccd520f ("fotg210-udc: Support optional external PHY"),
   8 the error code is re-assigned to 0 in fotg210_udc_probe(), if allocate or
   9 map memory fails after the assignment, it can't return an error code. Set
  10 the error code to -ENOMEM to fix this problem.
