pull-request: can-next 2021-08-25

Hello Jakub, hello David,

this is a pull request of 4 patches for net-next/master.

The first patch is by Cai Huoqing, and enables COMPILE_TEST for the
rcar CAN drivers.

Lad Prabhakar contributes a patch for the rcar_canfd driver, fixing a
redundant assignment.

The last 2 patches are by Tang Bin, target the mscan driver, and clean
up the driver by converting it to of_device_get_match_data() and
removing a useless BUG_ON.

regards,
Marc

From: Tang Bin <redacted>

Retrieve OF match data, it's better and cleaner to use
'of_device_get_match_data' over 'of_match_device'.

From: Tang Bin <redacted>

In the function mpc5xxx_can_probe(), the variable 'data' has already
been determined in the above code, so the BUG_ON() in this place is
useless, remove it.
