Subject: [net-next 17/39] can: m_can: m_can_class_allocate_dev(): remove impossible error return judgment

From: Xulin Sun <xulin.sun@...driver.com>

If the CAN net device has been successfully allocated, its private
data structure is impossible to be empty, remove this redundant error
return judgment.
