Merge tag 'linux-can-fixes-for-5.19-20220704' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can
Marc Kleine-Budde says:
====================
can 2022-07-04
The 1st patch is by Oliver Hartkopp, targets the BCM CAN protocol and
converts a costly synchronize_rcu() to call_rcu() to fix a performance
regression.
Srinivas Neeli's patch for the xilinx_can driver drops the brp limit
down to 1, as only the pre-production silicon have an issue with a brp
of 1.
The next patch is by Duy Nguyen and fixes the data transmission on
R-Car V3U SoCs in the rcar_canfd driver.
Rhett Aultman's patch fixes a DMA memory leak in the gs_usb driver.
Liang He's patch removes an extra of_node_get() in the grcan driver.
The next 2 patches are by me, target the m_can driver and fix the
timestamp handling used for peripheral devices like the tcan4x5x.
Jimmy Assarsson contributes 3 patches for the kvaser_usb driver and
fixes CAN clock and bit timing related issues.
The remaining 5 patches target the mcp251xfd driver. Thomas Kopp
contributes 2 patches to improve the workaround for broken CRC when
reading the TBC register. 3 patches by me add a missing
hrtimer_cancel() during the ndo_stop() callback, and fix the reading
of the Device ID register.

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.
