[patch V3 05/10] rslib: Add SPDX identifiers

[Thomas Gleixner]

From: Thomas Gleixner <tglx@xxxxxxxxxxxxx>

The Reed-Solomon library is based on code from Phil Karn who granted
permission to import it into the kernel under the GPL V2.

See commit 15b5423757a7 ("Shared Reed-Solomon ECC library") in the history
git tree at: git://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git

  ...
  The encoder/decoder code is lifted from the GPL'd userspace RS-library
  written by Phil Karn. I modified/wrapped it to provide the different
  functions which we need in the MTD/NAND code.
  ...

  "No objections at all. Just keep the authorship notices." -- Phil Karn

Add the proper SPDX identifiers according to
Documentation/process/license-rules.rst.
