[alsa-devel] [PATCH] ASoC: tpa6130a2: Revisit power-up sequence
by Jarkko Nikula 09 Nov '10

09 Nov '10

There are no known problems with current power-up sequence which first sets the /shutdown pin high and then enables the supply. However, swap the order so that the device is kept in shutdown/reset mode during the supply voltage transition since slowly rising voltages can usually cause problems if the device is not kept in reset.

[alsa-devel] [PATCH] ASoC: Ensure sane WM835x AIF configuration by default
by Mark Brown 09 Nov '10

Ensure that whatever ran before us leaves the WM835x with a sane default audio interface configuration as we do not override the companding, loopback or tristate settings and do not reset the chip at startup (as it is a PMIC).

[alsa-devel] [PATCH 1/2] ASoC: Update DAPM debug and error prints
by Jarkko Nikula 09 Nov '10

09 Nov '10

Switch printk and pr_ prints to dev_ variants. It is helpful to see parent device of DAPM context especially when there are multiple DAPM contexts (codecs currently). This is mostly simple conversion. Exceptions are in snd_soc_dapm_set_pin that prints also pin state, uniform "dapm: unknown pin" error prints from snd_soc_dapm_set_pin, snd_soc_dapm_force_enable_pin and snd_soc_dapm_ignore_suspend, and pop_dbg which is converted by an another patch.

[alsa-devel] question about sound/pci/ctxfi/ctpcm.c
by Julia Lawall 09 Nov '10

09 Nov '10

The file sound/pci/ctxfi/ctpcm.c contains the functions ct_pcm_playback_open and ct_pcm_capture_open that contain the following pattern of code: runtime->private_data = apcm; ... if (err < 0) { kfree(apcm); return err; } I wonder if this leaves a dangling pointer to apcm in runtime? The function ct_atc_pcm_free_substream on the other hand does set the private_data field to NULL after freeing apcm. But perhaps there is something in the calling context of open that ensures that if the open function fails, the private_data field of runtime will never be used? thanks, julia

[alsa-devel] [PATCH 17/17][trivial] Sound, OSS: Remove unnecessary casts of void ptr returning alloc function return values

Hi, The [vk][cmz]alloc(_node) family of functions return void pointers which it's completely unnecessary/pointless to cast to other pointer types since that happens implicitly. This patch removes such casts from sound/oss/ Signed-off-by: Jesper Juhl <jj(a)chaosbits.net> --- midibuf.c | 4 ++-- pss.c | 6 +++--- sequencer.c | 4 ++-- 3 files changed, 7 insertions(+), 7 deletions(-) diff --git a/sound/oss/midibuf.c b/sound/oss/midibuf.c index 782b3b8..ceedb1e 100644 --- a/sound/oss/midibuf.c +++ b/sound/oss/midibuf.c @@ -178,7 +178,7 @@ int MIDIbuf_open(int dev, struct file *file) return err; parms[dev].prech_timeout = MAX_SCHEDULE_TIMEOUT; - midi_in_buf[dev] = (struct midi_buf *) vmalloc(sizeof(struct midi_buf)); + midi_in_buf[dev] = vmalloc(sizeof(struct midi_buf)); if (midi_in_buf[dev] == NULL) { @@ -188,7 +188,7 @@ int MIDIbuf_open(int dev, struct file *file) } midi_in_buf[dev]->len = midi_in_buf[dev]->head = midi_in_buf[dev]->tail = 0; - midi_out_buf[dev] = (struct midi_buf *) vmalloc(sizeof(struct midi_buf)); + midi_out_buf[dev] = vmalloc(sizeof(struct midi_buf)); if (midi_out_buf[dev] == NULL) { diff --git a/sound/oss/pss.c b/sound/oss/pss.c index e19dd5d..9b800ce 100644 --- a/sound/oss/pss.c +++ b/sound/oss/pss.c @@ -859,7 +859,7 @@ static int pss_coproc_ioctl(void *dev_info, unsigned int cmd, void __user *arg, return 0; case SNDCTL_COPR_LOAD: - buf = (copr_buffer *) vmalloc(sizeof(copr_buffer)); + buf = vmalloc(sizeof(copr_buffer)); if (buf == NULL) return -ENOSPC; if (copy_from_user(buf, arg, sizeof(copr_buffer))) { @@ -871,7 +871,7 @@ static int pss_coproc_ioctl(void *dev_info, unsigned int cmd, void __user *arg, return err; case SNDCTL_COPR_SENDMSG: - mbuf = (copr_msg *)vmalloc(sizeof(copr_msg)); + mbuf = vmalloc(sizeof(copr_msg)); if (mbuf == NULL) return -ENOSPC; if (copy_from_user(mbuf, arg, sizeof(copr_msg))) { @@ -895,7 +895,7 @@ static int pss_coproc_ioctl(void *dev_info, unsigned int cmd, void __user *arg, case SNDCTL_COPR_RCVMSG: err = 0; - mbuf = (copr_msg *)vmalloc(sizeof(copr_msg)); + mbuf = vmalloc(sizeof(copr_msg)); if (mbuf == NULL) return -ENOSPC; data = (unsigned short *)mbuf->data; diff --git a/sound/oss/sequencer.c b/sound/oss/sequencer.c index e85789e..5ea1098 100644 --- a/sound/oss/sequencer.c +++ b/sound/oss/sequencer.c @@ -1646,13 +1646,13 @@ void sequencer_init(void) { if (sequencer_ok) return; - queue = (unsigned char *)vmalloc(SEQ_MAX_QUEUE * EV_SZ); + queue = vmalloc(SEQ_MAX_QUEUE * EV_SZ); if (queue == NULL) { printk(KERN_ERR "sequencer: Can't allocate memory for sequencer output queue\n"); return; } - iqueue = (unsigned char *)vmalloc(SEQ_MAX_QUEUE * IEV_SZ); + iqueue = vmalloc(SEQ_MAX_QUEUE * IEV_SZ); if (iqueue == NULL) { printk(KERN_ERR "sequencer: Can't allocate memory for sequencer input queue\n"); -- Jesper Juhl <jj(a)chaosbits.net> http://www.chaosbits.net/ Don't top-post http://www.catb.org/~esr/jargon/html/T/top-post.html Plain text mails only, please.
