Presence of hexadecimal address or symbol results in false warning
message by checkpatch.pl.
For example, running checkpatch on commit b8ad540dd4e4 ("mptcp: fix
memory leak in mptcp_subflow_create_socket()") results in warning:
WARNING:REPEATED_WORD: Possible repeated word: 'ff'
00 00 00 00 00 00 00 00 00 2f 30 0a 81 88 ff ff ........./0.....
Similarly, the presence of list command output in commit results in
an unnecessary warning.
For example, running checkpatch on commit 899e5ffbf246 ("perf record:
Introduce --switch-output-event") gives:
WARNING:REPEATED_WORD: Possible repeated word: 'root'
dr-xr-x---. 12 root root 4096 Apr 27 17:46 ..
Here, it reports 'ff' and 'root' to be repeated, but it is in fact part
of some address or code, where it has to be repeated.
In these cases, the intent of the warning to find stylistic issues in
commit messages is not met and the warning is just completely wrong in
this case.
To avoid these warnings, add an additional regex check for the directory
permission pattern and avoid checking the line for this class of
warning. Similarly, to avoid hex pattern, check if the word consists of
hex symbols and skip this warning if it is not among the common english
words formed using hex letters.
A quick evaluation on v5.6..v5.8 showed that this fix reduces
REPEATED_WORD warnings by the frequency of 1890.
A quick manual check found all cases are related to hex output or list
command outputs in commit messages.

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.
