Bjorn Helgaas ec4b595572 PCI: switchtec: Return -EFAULT for copy_to_user() errors ... [ Upstream commit ddc10938e0 ] switchtec_dev_read() didn't handle copy_to_user() errors correctly: it assigned "rc = -EFAULT", but actually returned either "size", -ENXIO, or -EBADMSG instead. Update the failure cases to unlock mrpc_mutex and return -EFAULT directly.
