2013-03-11ALSA: Make snd_BUG_ON() always evaluate and return the conditional expressionChristine Spang1-7/+5
Having snd_BUG_ON() only evaluate its conditional when CONFIG_SND_DEBUG is set leads to frequent bugs, since other similar macros in the kernel have different behavior. Let's make snd_BUG_ON() act like those macros so it will stop being accidentally misused. Signed-off-by: Christine Spang <christine.spang@oracle.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2013-02-05ALSA: Fix wrong description about hw constraintsTakashi Iwai1-19/+20
The definitions of hw constraint functions are wrongly placed, and the description about the function is also wrong. hw_rule_channels_by_format actually refines the channels depending on the format, not vice versa.

2012-12-07ALSA: DocBook: Remove the description of __dev*Takashi Iwai1-57/+28
Remove obsoleted __devinit* and __devexit* from the example codes and the descriptions, or modified the descriptions a bit to match with the current situation. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2011-12-19ALSA: module_param: make bool parameters really boolRusty Russell1-1/+1
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>
2011-09-14ALSA: mpu401: clean up interrupt specificationClemens Ladisch1-15/+21
The semantics of snd_mpu401_uart_new()'s interrupt parameters are somewhat counterintuitive: To prevent the function from allocating its own interrupt, either the irq number must be invalid, or the irq_flags parameter must be zero. At the same time, the irq parameter being invalid specifies that the mpu401 code has to work without an interrupt allocated by the caller. This implies that, if there is an interrupt and it is allocated by the caller, the irq parameter must be set to a valid-looking number which then isn't actually used. With the removal of IRQF_DISABLED, zero becomes a valid irq_flags value, which forces us to handle the parameters differently. This patch introduces a new flag MPU401_INFO_IRQ_HOOK for when the device interrupt is handled by the caller, and makes the allocation of the interrupt to depend only on the irq parameter. As suggested by Takashi, the irq_flags parameter was dropped because, when used, it had the constant value IRQF_DISABLED.

2009-03-09ALSA: Move ALSA docbooks to be with the rest of the kernel docbooksRandy Dunlap1-0/+6216
Move ALSA docbooks to be with the rest of the kernel docbooks and add them to the Makefile so that they build. Latter required a few minor changes to alsa .tmpl files. (I did not remove all of the trailing whitespace in the .tmpl files.)
