2017-09-07ALSA: asihpi: Kill BUG_ON() usagesTakashi Iwai1-5/+1
BUG_ON() is the worst choice for a trivial sanity check. Either it should be removed or replaced with a softer one like WARN_ON() if still really needed. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2016-09-02ALSA: constify snd_pcm_ops structuresJulia Lawall1-2/+2
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>

2015-01-02ALSA: asihpi: Remove always NULL parameterLars-Peter Clausen1-7/+2
snd_asihpi_hpi_new() takes a pointer to a pointer of a hwdep where if this parameter is provided the newly allocated hwdep is stored. All callers pass NULL though, so remove the parameter. This makes the code a bit cleaner and shorter. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2014-11-23ALSA: asihpi: Add support for stream interrupt.Eliot Blennerhassett1-29/+148
Some cards have a so-called low-latency mode, in which they present a single multichannel stream with no mixing or samplerate conversion. In this mode the card can generate an interrupt per internal processing block (typically 32 or 64 frames) Signed-off-by: Eliot Blennerhassett <eliot@blennerhassett.gen.nz> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2014-11-09ALSA: pcm: Add snd_pcm_stop_xrun() helperTakashi Iwai1-4/+1
Add a new helper function snd_pcm_stop_xrun() to the standard sequnce lock/snd_pcm_stop(XRUN)/unlock by a single call, and replace the existing open codes with this helper. The function checks the PCM running state to prevent setting the wrong state, too, for more safety. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2014-08-12PCI: Remove DEFINE_PCI_DEVICE_TABLE macro useBenoit Taine1-1/+1
We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to meet kernel coding style guidelines. This issue was reported by checkpatch.

2013-06-28ALSA: Replace the magic number 44 with constTakashi Iwai1-1/+1
The char arrays with size 44 are for the name string of snd_ctl_elem_id. Define the constant and replace the raw numbers with it for clarifying better. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-04-29ALSA: asihpi: add format support check in snd_card_asihpi_capture_formatsEldad Zack1-1/+1
Some Asihpi formats are not supported or invalid, and their mapping to ALSA format is set to -1. Before performing the format conversion into ALSA bitwise formats, add a consistency check for the requested format, as done in snd_card_asihpi_playback_formats(). Compile tested only.

2011-12-19ALSA: module_param: make bool parameters really boolRusty Russell1-2/+2
module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-11-01sound: Add module.h to the previously silent sound usersPaul Gortmaker1-0/+1

In the sound/ directory there are two files (flagged by 'make versioncheck'); sound/pci/asihpi/asihpi.c and sound/soc/codecs/wm8991.c that include linux/version.h although they don't need it.

2011-06-10ALSA: Use KBUILD_MODNAME for pci_driver.name entriesTakashi Iwai1-1/+1
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. This patch converts the all pci_driver.name entries in sound/pci/* to use KBUILD_MODNAME for more unified appearance. Signed-off-by: Takashi Iwai <tiwai@suse.de>
