net: marvell: fix a missing check of acpi_match_device
When acpi_match_device fails, its return value is NULL. Directly using the return value without a check may result in a NULL-pointer dereference. The fix checks if acpi_match_device fails, and if so, returns -EINVAL. Signed-off-by:Kangjie Lu <kjlu@umn.edu> Signed-off-by:
