[PATCH 0/2] selftests: fix typos and repeated words in comments

[Hemanth Selam]

This corrects 2 misspellings and repeated words in comments.  Each is a
separate patch so that any one of them can be dropped without touching
the rest.

Nothing outside comments changes.  Every touched C file was checked by
dropping its comments, replacing each string literal with a placeholder
and collapsing whitespace; what remained was identical before and after,
so the compiled code cannot differ.

The mistakes were found with scripts/checkpatch.pl against the list in
scripts/spelling.txt.  The scanning, the edits and the changelogs were
produced with Cursor running the claude-opus-5 model, from a request to
find and fix spelling mistakes across the tree, and every correction was
then re-checked by the comparison described above.  Words that name an
identifier were left alone deliberately, even when they read as typos,
because correcting the prose would make the comment disagree with the
code it describes.

Tested by building x86_64 defconfig at v7.3-rc1-269-gbc35965f6940, which
is clean.  Nothing else was built, so any patch touching code that
x86_64 defconfig does not compile has been read but not compiled.
