This is a preparation patch to convert the driver to the rx-offload helper. In rx-offload RX, TX-done and CAN error handling are done in the IRQ handler, SKB are pushed to the network stack in the NAPI poll function. Move the CAN frame error handling from the NAPI function at91_poll() to the IRQ handler at91_poll(). To reflect this change, rename at91_poll_err() to at91_irq_err_frame().

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.
