Sean Nyekjaer 1ad3ee211d can: tcan4x5x: tcan4x5x_can_probe(): get the device out of standby before register access ... commit 3069ce620d upstream. The m_can tries to detect if Non ISO Operation is available while in standby mode, 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 goes in standby mode. The m_can driver tries to access the control register but fails due to the device being in standby mode. So this patch will put the tcan device in normal mode before the m_can driver does the initialization.
