====================
pull-request: can-next 2024-03-04

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

The 1st patch is by Jimmy Assarsson and adds support for the Leaf v3
to the kvaser_usb driver.

Martin Jocić's patch targets the kvaser_pciefd driver and adds support
for the Kvaser PCIe 8xCAN device.

Followed by a patch by me that adds a missing a cpu_to_le32() to the
gs_usb driver, the change is not critical as the assigned value is 0.

The last patch is also by me and replaces a literal 256 with a proper
define.
