* [ALSA] Remove nested mutexes in seq_ports.cTakashi Iwai2006-06-22
| | | | | | | | Removed nested mutexes in the removal routine of port connections. The port is guaranteed to be offline before calling it, so no mutex is needed. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* [ALSA] Remove bogus check of mmap_count in snd_pcm_release()Takashi Iwai2006-06-22
| | | | | | | Removed a bogus check of mmap_count in snd_pcm_release(). This is no longer true for the shared streams. Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | | | | | | Removed zero-initializations of static variables. A tiny optimization. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* [ALSA] Fix pcm-draining of capture stream in PCM middle layerTakashi Iwai2006-06-22
| | | | | | | | Fix the draining of PCM capture stream in the PCM middle layer. snd_pcm_drain() ignored capture streams, but it should change the state to SNDRV_PCM_DRAINING. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* [ALSA] Fix rwlock around snd_iprintf() in sound coreTakashi Iwai2006-06-22
| | | | | | | | | Fixed rwlock around snd_iprintf() in sound core part. Replaced with mutex. Also, make mutex and flags static variables with addition of snd_card_locked() function (just for sound.c). Signed-off-by: Takashi Iwai <tiwai@suse.de>
* [ALSA] rawmidi: add get_port_info callback for sequencer information flagsClemens Ladisch2006-06-22
