Subject: [PATCH 5.4 37/62] can: m_can: m_can_class_unregister(): remove erroneous m_can_clk_stop()

From: Marc Kleine-Budde <mkl@...gutronix.de>

commit c4aec381ab98c9189d47b935832541d520f1f67f upstream.

In m_can_class_register() the clock is started, but stopped on exit. When
calling m_can_class_unregister(), the clock is stopped a second time.

This patch removes the erroneous m_can_clk_stop() in  m_can_class_unregister().
