0704c5743694 (can: m_can_platform: remove unnecessary m_can_class_resume() call) removed the m_can_class_resume() call in the runtime resume path to get rid of a infinite recursion, so the runtime resume now only handles the device clocks. Unfortunately it did not remove the complementary m_can_class_suspend() call in the runtime suspend function, so those paths are now unbalanced, which causes the pinctrl state to get stuck on the "sleep" state, which breaks all CAN functionality on SoCs where this state is defined. Remove the m_can_class_suspend() call to fix this.
