Consolidate and unify state change handling

Hi,

Here are my patches to improve consistency of error-state handling between platforms.

These are also my first patches posted to the linux kernel, so I apologise in advance if I'm doing something wrong.

Andri Yngvason (4):
can: dev: Add generic error-state-change handling
can: flexcan: Use generic error-state-change handling
can: mscan: Use generic error-state-change handling
can: sja1000: Use generic error-state-change handling
