[PATCH 1/7] can: m_can: m_can_plat_remove(): add missing pm_runtime_disable()

From: Marc Kleine-Budde
Date: Tue Aug 12 2025 - 13:38:06 EST


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.
