Hello Jakub, hello David,

this is a pull request of 12 patches for net-next/master.

The first two patches are by me and fix typos on the CAN gw protocol and the
flexcan driver.

The next patch is by Vincent Mailhol and targets the CAN driver infrastructure,
it exports the function that converts the CAN state into a human readable
string.

A patch by me, which target the CAN driver infrastructure, too, makes the
calculation in can_fd_len2dlc() more readable.

A patch by Tom Rix fixes a checkpatch warning in the mcba_usb driver.

The next seven patches target the mcp251xfd driver. Su Yanjun's patch replaces
several hardcoded assumptions when calling regmap, by using
regmap_get_val_bytes(). The remaining patches are by me. First an open coded
check is replaced by an existing helper function, then in the TX path the
padding for CAN-FD frames is cleaned up. The next two patches clean up the RTR
frame handling in the RX and TX path. Then support for len8_dlc is added. The
last patch adds BQL support.

regards,
Marc
