Subject: pull-request: can 2021-01-07

Hello Jakub, hello David,

this is a pull request of 6 patches for net/master.

The first patch is by me for the m_can driver and removes an erroneous
m_can_clk_stop() from the driver's unregister function.

The second patch targets the tcan4x5x driver, is by me, and fixes the bit
timing constant parameters.

The next two patches are by me, target the mcp251xfd driver, and fix a race
condition in the optimized TEF path (which was added in net-next for v5.11).
The similar code in the RX path is changed to look the same, although it
doesn't suffer from the race condition.

A patch by Lad Prabhakar updates the description and help text for the rcar CAN
driver to reflect all supported SoCs.

In the last patch Sriram Dash transfers the maintainership of the m_can driver
to Pankaj Sharma.

regards,
Marc
