This is a preparation patch to convert the driver to make use of the rx-offload helper. With rx-offload the received CAN frames are sorted by their timestamp. Regular CAN RX'ed and TX'ed CAN frames are timestamped by the hardware. Error events are not. Introduce a new function at91_alloc_can_err_skb() the allocates an error SKB and reads the current timestamp from the controller.

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.
