Stanley.Yang d6dac2bc12 drm/amdgpu: fix channel index mapping for SIENNA_CICHLID
Pmfw read ecc info registers in the following order,
     umc0: ch_inst 0, 1, 2 ... 7
     umc1: ch_inst 0, 1, 2 ... 7
The position of the register value stored in eccinfo
table is calculated according to the below formula,
     channel_index = umc_inst * channel_in_umc + ch_inst
Driver directly use the index of eccinfo table array
as channel index, it's not correct, driver needs convert
eccinfo table array index to channel index according to
channel_idx_tbl.

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.
