I would, in essence, agree with this.  Not because of lint, but such void
cast, primarily, demonstrates to developer/reader that function returns some
value and we deliberately ignore it.

However, functions like printf(), memset() and friends are common and well
known cases where return value is usually ignored.  We do not cast them in
kernel code (nor I think we should).  If lint complains about ignoring of
memset() return value - I am really not interested. :)
