Commit 227619c3ff7c ("can: m_can: move runtime PM enable/disable to m_can_platform") moved the PM runtime enable from the m_can core driver into the m_can_platform. That patch forgot to move the pm_runtime_disable() to m_can_plat_remove(), so that unloading the m_can_platform driver causes an "Unbalanced pm_runtime_enable!" error message. Add the missing pm_runtime_disable() to m_can_plat_remove() to fix the problem.
