[PATCH v2 3/3] staging: comedi: mite: Replace function mite_request_channel_in_range()

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

 



Remove function mite_request_channel_in_range as all it does is call
__mite_request_channel.
Rename __mite_request_channel to mite_request_channel_in_range and
change its type from static to non-static to maintain compatibility with
call sites.
Change only remaining call site of __mite_request_channel to call
mite_request_channel_in_range_instead.
Issue found with Coccinelle.
