Marc Kleine-Budde eb94b74ccd can: mcp251xfd: simplify UINC handling
In the patches:

| 1f652bb6ba can: mcp25xxfd: rx-path: reduce number of SPI core requests to set UINC bit
| 68c0c1c7f9 can: mcp251xfd: tef-path: reduce number of SPI core requests to set UINC bit

the setting of the UINC bit in the TEF and RX FIFO was batched into a
single SPI message consisting of several transfers. All transfers but
the last need to have the cs_change set to 1.

In the original patches the array of prepared transfers is send from
the beginning with the length depending on the number of read TEF/RX
objects. The cs_change of the last transfer is temporarily set to
0 during send.

This patch removes the modification of cs_change by preparing the last
transfer with cs_change to 0 and all other to 1. When sending the SPI
message the driver now starts with an offset into the array, so that
it always ends on the last entry in the array, which has the cs_change
set to 0.

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.
