Subject: [PATCH] pcm: Close event timer in pcm_hw plugin
|
||||
|
||||
Dan McCombs discovered that snd_pcm_close() invocations are not leading
|
||||
to associated timers being closed, which results in successively more
|
||||
timers being created but not freed.
|
||||
|
||||
Original patch from Daniel T Chen <crimsun@ubuntu.com>.
