When introducing support for R-Car V3U, which has 8 instead of 2
channels, the ECC error bitmask was extended to take into account the
extra channels, but rcar_canfd_global_error() was not updated to act
upon the extra bits.
Replace the RCANFD_GERFL_EEF[01] macros by a new macro that takes the
channel number, fixing R-Car V3U while simplifying the code.
Fixes: 45721c406d ("can: rcar_canfd: Add support for r8a779a0 SoC")

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.
