* ALSA: constify snd_pcm_ops structuresJulia Lawall2016-09-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Check for snd_pcm_ops structures that are only stored in the ops field of a snd_soc_platform_driver structure or passed as the third argument to snd_pcm_set_ops. The corresponding field or parameter is declared const, so snd_pcm_ops structures that have this property can be declared as const also. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r disable optional_qualifier@ identifier i; position p; @@ static struct snd_pcm_ops i@p = { ... }; @ok1@ identifier r.i; struct snd_soc_platform_driver e; position p; @@ e.ops = &i@p; @ok2@ identifier r.i; expression e1, e2; position p; @@ snd_pcm_set_ops(e1, e2, &i@p) @bad@ position p != {r.p,ok1.p,ok2.p}; identifier r.i; struct snd_pcm_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct snd_pcm_ops i = { ... }; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: pcxhr: Fix missing mutex unlockTakashi Iwai2016-04-211-0/+1
| | | | | | | | | | | The commit [9bef72bdb26e: ALSA: pcxhr: Use nonatomic PCM ops] converted to non-atomic PCM ops, but shamelessly with an unbalanced mutex locking, which leads to the hangup easily.

* ALSA: pcxhr: convert timeval to ktime_tAya Mahfouz2014-10-282-8/+12
| | | | | | | | | | | | This patch is concerned with migrating the time variables in the pcxhr module found in the sound driver. The changes are concerend with the y2038 problem where timeval will overflow in the year 2038. ktime_t was used instead of timeval to get the wall time. The difference is displayed now in nanoseconds instead of microseconds.

* ALSA: PCI: Remove superfluous pci_set_drvdata(pci, NULL) at removeTakashi Iwai2013-05-291-1/+0
| | | | | | | | | | | | | As drvdata is cleared to NULL at probe failure or at removal by the driver core, we don't have to call pci_set_drvdata(pci, NULL) any longer in each driver. The only remaining pci_set_drvdata(NULL) is in azx_firmware_cb() in hda_intel.c. Since this function itself releases the card instance, we need to clear drvdata here as well, so that it won't be released doubly in the remove callback. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: Make snd_printd() and snd_printdd() inlineTakashi Iwai2013-01-251-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Because currently snd_printd() and snd_printdd() macros are expanded to empty when CONFIG_SND_DEBUG=n, a compile warning like below appears sometimes, and we had to covert it by ugly ifdefs: sound/pci/hda/patch_sigmatel.c: In function ‘stac92hd71bxx_fixup_hp’: sound/pci/hda/patch_sigmatel.c:2434:24: warning: unused variable ‘spec’ [-Wunused-variable] For "fixing" these issues better, this patch replaces snd_printd() and snd_printdd() definitions with empty inline functions instead of macros. This should have the same effect but shut up warnings like above. But since we had already put ifdefs, changing to inline functions would trigger compile errors. So, such ifdefs is removed in this patch. In addition, snd_pci_quirk name field is defined only when CONFIG_SND_DEBUG_VERBOSE is set, and the reference to it in snd_printdd() argument triggers the build errors, too. For avoiding these errors, introduce a new macro snd_pci_quirk_name() that is defined no matter how the debug option is set.

| | | | | | | | | The name argument of request_irq() appears in /proc/interrupts, and it's quite ugly when the name entry contains a space or special letters.

| | | | | | | | | | | | The convention for pci_driver.name entry in kernel drivers seem to be the module name or equivalent ones. But, so far, almost all PCI sound drivers use more verbose name like "ABC Xyz (12)", and these are fairly confusing when appearing as a file name.
