[PATCH can 0/4] can: fix probing and use of device_get_match_data()

[Marc Kleine-Budde <mkl@pengutronix.de>]

With patch 5e6c3454b405 ("net: can: Use device_get_match_data()") several
CAN drivers were converted to device_get_match_data(). The author assumed
that error checking for matching and match data is not necessary.

This misses the fact that that drivers on the platform bus can forcefully
bound using driver_override and device_get_match_data() will return NULL.

By using device_get_match_data(), this change broke probing for
m68k/coldfire, which still uses platform devices.

This series adds missing NULL pointer checks and fixes probing for the
flexcan on m68k/coldfire.
