Name
snd_BUG_ON —
debugging check macro
Arguments
cond
condition to evaluate
Description
When CONFIG_SND_DEBUG is set, this macro evaluates the given condition,
and call WARN and returns the value if it's non-zero.
When CONFIG_SND_DEBUG is not set, this just returns zero, and the given
condition is ignored.
NOTE
the argument won't be evaluated at all when CONFIG_SND_DEBUG=n.
Thus, don't put any statement that influences on the code behavior,
such as pre/post increment, to the argument of this macro.
If you want to evaluate and give a warning, use standard WARN_ON.
