2011-11-10ALSA: vmaster - Free slave-links when freeing the master elementTakashi Iwai1-4/+14
When freeing the vmaster master element, we should release slave-links properly, not only assumig that slaves will be freed soon later. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-10-31sound: Add export.h for THIS_MODULE/EXPORT_SYMBOL where neededPaul Gortmaker1-0/+1
These aren't modules, but they do make use of these macros, so they will need export.h to get that definition. Previously, they got it via the implicit module.h inclusion. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

2011-02-14ALSA: core: sparse cleanupsClemens Ladisch1-1/+1
Change the core code where sparse complains. In most cases, this means just adding annotations to confirm that we indeed want to do the dirty things we're doing. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-06-17ALSA: Add new TLV types for dBwith min/maxTakashi Iwai1-2/+6
Add new types for TLV dB scale specified with min/max values instead of min/step since the resolution can't match always with the one a device provides. For example, usb audio devices give 1/256 dB resolution while ALSA TLV is based on 1/100 dB resolution. The new min/max types have less problems because the possible rounding error happens only at min/max. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-03-09ALSA: add snd_ctl_add_slave_uncached()Takashi Iwai1-17/+29
Added snd_ctl_add_slave_uncached() function to add a slave element with volatile controls. The values of normal slave elements are supposed to be cachable, i.e. they are changed only via the put callbacks. OTOH, when a slave element is volatile and its values may be changed by other reason (e.g. hardware status change), the values will get inconsistent. The new function allows the slave elements with volatile changes. When the slave is tied with this call, the native get callback is issued at each time so that the values are always updated.

2008-04-24[ALSA] Keep private TLV entry in vmaster itselfTakashi Iwai1-3/+6
Use a private array for TLV entries of virtual master controls instead of (supposed) static array. This cleans up the existing codes. Also, now vmaster assumes the simple dB-range TLV that is the only type it can handle. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-04-24[ALSA] Move vmaster code to sound coreTakashi Iwai1-0/+368
Move the codes for virtual master controls to sound core part so that not only hda-intel drivers can use it. Signed-off-by: Takashi Iwai <tiwai@suse.de>
