The m_can tries to detect if Non ISO Operation is available while in standby, this function results in the following error:
tcan4x5x spi2.0 (unnamed net_device) (uninitialized): Failed to init module tcan4x5x spi2.0: m_can device registered (irq=84, version=32) tcan4x5x spi2.0 can2: TCAN4X5X successfully initialized.
When the tcan device comes out of reset it comes out in standby mode. The m_can driver tries to access the control register but fails due to the device is in standby mode. So this patch will put the tcan device in normal mode before the m_can driver does the initialization.

Applied both to linux-can.
