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: fix drivers needing module.h not moduleparam.hPaul Gortmaker1-1/+1
The implicit presence of module.h lured several users into incorrectly thinking that they only needed/used modparam.h but once we clean up the module.h presence, these will show up as build failures, so fix 'em now. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-09-14ALSA: mpu401: clean up interrupt specificationClemens Ladisch1-2/+3
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.

2011-06-10ALSA: use KBUILD_MODNAME for request_irq argument in sound/pci/*Takashi Iwai1-1/+1
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. In general, it's simpler and more readable when the module name appears there, so let's replace all entries with KBUILD_MODNAME. Signed-off-by: Takashi Iwai <tiwai@suse.de>
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>

2010-03-24ALSA: cmipci: work around invalid PCM pointerClemens Ladisch1-3/+11
When the CMI8738 FRAME2 register is read, the chip sometimes (probably when wrapping around) returns an invalid value that would be outside the programmed DMA buffer. This leads to an inconsistent PCM pointer that is likely to result in an underrun. To work around this, read the register multiple times until we get a valid value; the error state seems to be very short-lived.

2008-04-24[ALSA] Fix synchronize_irq() bugs, redundanciesJeff Garzik1-2/+0
free_irq() calls synchronize_irq() for you, so there is no need for drivers to manually do the same thing (again). Thus, calls where sync-irq immediately precedes free-irq can be simplified. However, during this audit several bugs were noticed, where free-irq is preceded by a "irq >= 0" check... but the sync-irq call is not covered by the same check. So, where sync-irq could not be eliminated completely, the missing check was added. Signed-off-by: Jeff Garzik <jgarzik@redhat.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
