Merge tag 'linux-can-next-for-6.7-20231005' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next

Marc Kleine-Budde says:

====================
pull-request: can-next 2023-10-05

The first patch is by Miquel Raynal and fixes a comment in the sja1000
driver.

Vincent Mailhol contributes 2 patches that fix W=1 compiler warnings
in the etas_es58x driver.

Jiapeng Chong's patch removes an unneeded NULL pointer check before
dev_put() in the CAN raw protocol.

A patch by Justin Stittreplaces a strncpy() by strscpy() in the
peak_pci sja1000 driver.

The next 5 patches are by me and fix the can_restart() handler and
replace BUG_ON()s in the CAN dev helpers with proper error handling.

The last 27 patches are also by me and target the at91_can driver.
First a new helper function is introduced, the at91_can driver is
cleaned up and updated to use the rx-offload helper.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
