Subject: checkpatch: use python3 to find codespell dictionary
Commit 0ee3e7b8893e ("checkpatch: get default codespell dictionary path
from package location") introduced the ability to search for the codespell
dictionary rather than hardcoding its path.
codespell requires Python 3.6 or above, but on some systems, the python
executable is a Python 2.7 interpreter. In this case, searching for the
dictionary fails, subsequently making codespell fail:
No codespell typos will be found - file '/usr/share/codespell/dictionary.txt': No such file or directory
So, use python3 to remove ambiguity.
In addition, when searching for dictionary.txt, do not check if the
codespell executable exists since,
- checkpatch.pl only uses dictionary.txt, not the codespell
executable.
- codespell can be installed via a Python package manager, in which
case the codespell executable may not be present in a typical $PATH,
but a dictionary does exist.
