12 cond
13 condition to evaluate
14
16 When CONFIG_SND_DEBUG is set, this macro evaluates the given condition,
17 and call WARN and returns the value if it's non-zero.
18
19 When CONFIG_SND_DEBUG is not set, this just returns zero, and the given
20 condition is ignored.
21
23 the argument won't be evaluated at all when CONFIG_SND_DEBUG=n. Thus,
24 don't put any statement that influences on the code behavior, such as
25 pre/post increment, to the argument of this macro. If you want to
26 evaluate and give a warning, use standard WARN_ON.
