mainlining shenanigans

Function es58x_fd_rx_event() invokes the es58x_check_msg_len() macro: | ret = es58x_check_msg_len(es58x_dev->dev, *rx_event_msg, msg_len); While doing so, it dereferences an uninitialized variable: *rx_event_msg. This is actually harmless because es58x_check_msg_len() only uses preprocessor macros (sizeof() and __stringify()) on *rx_event_msg. c.f. [1]. Nonetheless, this pattern is confusing so the lines are reordered to make sure that rx_event_msg is correctly initialized. This patch also fixes a false positive warning reported by cppcheck: | cppcheck possible warnings: (new ones prefixed by >>, may not be real problems) | | In file included from drivers/net/can/usb/etas_es58x/es58x_fd.c: | >> drivers/net/can/usb/etas_es58x/es58x_fd.c:174:8: warning: Uninitialized variable: rx_event_msg [uninitvar] | ret = es58x_check_msg_len(es58x_dev->dev, *rx_event_msg, msg_len); | ^ [1] https://elixir.bootlin.com/linux/v5.16/source/drivers/net/can/usb/etas_es58x/es58x_core.h#L467 Link: https://lore.kernel.org/all/20220306101302.708783-1-mailhol.vincent@wanadoo.fr Signed-off-by: Vincent Mailhol <mailhol.vincent@wanadoo.fr> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> |

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.
