usb: ohci-da8xx: ensure error return on variable error is set
Currently when an error occurs when calling devm_gpiod_get_optional or
calling gpiod_to_irq it causes an uninitialized error return in variable
'error' to be returned. Fix this by ensuring the error variable is set
from da8xx_ohci->oc_gpio and oc_irq.
Thanks to Dan Carpenter for spotting the uninitialized error in the
gpiod_to_irq failure case.
Addresses-Coverity: ("Uninitialized scalar variable")
