Hi Simran,

It's helpful to state right in the subject line what you removed.
ie.  remove unused function atomisp_set_stop_timeout()

If you do that, scan's or grep'ing the git log pretty oneline's can 
easily see this without having to dig into the log.

(gitpretty='git log --pretty=oneline --abbrev-commit')

Can you share to Outreachy group how you found this?  By inspection
or otherwise??

Thanks,
alisons
