From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently when an error in da8xx_ohci->oc_gpio occurs it causes an
uninitialized error return in variable 'error' to be returned. Fix
this by ensuring the error variable is set to the error value in
da8xx_ohci->oc_gpio.
Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: d193abf1c913 ("usb: ohci-da8xx: add vbus and overcurrent gpios")
