From: Asbjørn Sloth Tønnesen <redacted> [ Upstream commit e25714466abd9d96901b15efddf82c60a38abd86 ] Explicitly set 'rc' (return code), before jumping to the unlock and return path. By not having any code depend on that 'rc' remains at it's initial value of -EINVAL, then we can re-use 'rc' for the return code of function calls in subsequent patches. Only compile tested.
