[PATCH v1] staging: media: Remove unused function atomisp_set_stop_timeout()

[simran singhal]

The function atomisp_set_stop_timeout on being called, simply returns
back. The function hasn't been mentioned in the TODO and doesn't have
FIXME code around. Hence, atomisp_set_stop_timeout and its calls have been
removed.

This was done using Coccinelle.

You should also cc: the developers doing all of the current work on this
driver, Alan Cox, to get their comment if this really is something that
can be removed or not.

thanks,

Greg I have cc'd all the developers which script get_maintainer.pl showed:

$ git show HEAD | perl scripts/get_maintainer.pl --separator ,
--nokeywords --nogit --nogit-fallback --norolestats

Sometimes people do a lot of work on something without being the
maintainer.  You can see who has done this using git log.  Dropping some
of the "no" arguments might give you the same information, but in practice
the results tend to be an overapproximation...
