Subject: Re: [PATCH] drivers/net/can/m_can/Kconfig: Let CAN_M_CAN depend on
 HAS_IOMEM

Hi Chen Gang


I think commit message should be short and proper.

We can remove *drivers/net/can/m_can/Kconfig* in the commit, just
give *can: Kconfig: *

commit message like : *can: Kconfig: Fix CAN_M_CAN dependency*
