[PATCH v4 2/4] can: m_can: make m_can_start and m_can_stop symmetric
From: Quentin Schulz
Date: Fri May 05 2017 - 09:50:49 EST
This moves clocks gating outside of the m_can_stop function as the
m_can_start function does not (and cannot, at least in current
implementation) ungate clocks. This way, both functions can now be used
symmetrically.
