[PATCH v2 8/8] Documentation: HID: uhid editing & corrections

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Do basic editing & correction to hid-alps.rst:
- correct a file name (.txt -> .rst)
- use less hyphenation when not needed
- fix grammar & punctuation
- fix article adjectives
- fix typos/spellos
- use HID instead of hid consistently
