| |
The use of snd_printd_ratelimit() supresses superfluous output from printk_ratelimit() when CONFIG_SND_DEBUG is not defined. For example,
[ 43.753692] snd_pcm_update_hw_ptr0: 26 callbacks suppressed [ 48.822131] snd_pcm_update_hw_ptr0: 25 callbacks suppressed [ 53.894953] snd_pcm_update_hw_ptr0: 25 callbacks suppressed [ 58.997761] snd_pcm_update_hw_ptr0: 25 callbacks suppressed [ 64.100952] snd_pcm_update_hw_ptr0: 25 callbacks suppressed
fills the log even when no debug output is actually produced.
