[PATCH 00/22] usb: fix spelling mistakes in comments

[Shunbo Shi]

Cover-letter:

Hi Greg,

This series fixes misspelled words in code comments across 22
subdirectories of drivers/usb/, found with codespell.  All changes
are comment-only: no identifiers, strings, macros or code are
touched (verified mechanically - every modified line starts with
a comment marker).

Words that are USB domain terms, device or product names,
people's names, or common informal variants are deliberately
left untouched.

[PATCH v2 00/22] usb: fix spelling mistakes in comments

[Shunbo Shi]

Cover-letter:

Hi Greg,

v2 of this series fixes an issue in v1 spotted by the Sashiko AI
review: due to a rebase slip, the "usb: usbip" patch (22/22)
carried an unrelated hunk for drivers/usb/serial/ftdi_sio.h that
reverted a spelling fix made in the "usb: serial" patch (19/22).
v2 drops the ftdi_sio.h changes entirely from both patches (the
file is left untouched, as the word in question was deliberately
not fixed); all other patches are identical to v1.

This series fixes misspelled words in code comments across 22
subdirectories of drivers/usb/, found with codespell.  All changes
are comment-only: no identifiers, strings, macros or code are
touched (verified mechanically - every modified line starts with
a comment marker).

No functional changes.

Hi,

Not 100% sure, but hasn't Greg KH indicated no interest in such patches
for drivers outside of staging?

I don't like them either, IMO the noise added to git-blame is usually
more annoying in practice than original errors.

So words that don't exist have been replaced with words that exist.
But the text is still wrong.

These are just two random examples near the end, I haven't read even
a fraction of the whole thing.

Another issue I have seen in those patches are fixes to comments that
aren't even true anymore, but the author has no idea of course.

Regards,
Michal
