From 8a3f3f24a829c80d8d451e75e887912c3905dfd0 Mon Sep 17 00:00:00 2001 From: Quentin Schulz Date: Fri, 5 May 2017 15:50:31 +0200 Subject: [PATCH] can: m_can: make m_can_start and m_can_stop symmetric 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.
