Merge patch series "can: m_can: various cleanups"

Marc Kleine-Budde <mkl@pengutronix.de> says:

While working on the m_can driver, I created several cleanups commits, make
m_can_init_ram() static, rename hrtimer function, convert debugging and
error output to netdev_(), replace open coded register write by
m_can_write(), remove not needed error messages and sanity checks and don't
wake up hte controller during m_can_get_berr_counter() if the interface is
down.
