2012-12-07ALSA: drivers: remove __dev* attributesBill Pemberton14-99/+99
CONFIG_HOTPLUG is going away as an option. As result the __dev* markings will be going away. Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit. Signed-off-by: Bill Pemberton <wfp5p@virginia.edu> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2012-10-21ALSA: aloop - Close races at restarting the streamTakashi Iwai1-17/+19
There are small races opened in the check of running bit and the timer lock. Instead of adding yet more flag, just protect the whole racy codes with the existing cable->lock. As a bonus, we can get rid of timer_lock now. Reported-and-tested-by: Omair Mohammed Abdullah <omair.m.abdullah@linux.intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2012-10-06ALSA: aloop - add locking to timer accessOmair Mohammed Abdullah1-0/+6
When the loopback timer handler is running, calling del_timer() (for STOP trigger) will not wait for the handler to complete before deactivating the timer. The timer gets rescheduled in the handler as usual. Then a subsequent START trigger will try to start the timer using add_timer() with a timer pending leading to a kernel panic. Serialize the calls to add_timer() and del_timer() using a spin lock to avoid this.

The irq field of struct snd_mpu401 is supposed to be initialized to -1. Since it's set to zero as of now, a probing error before the irq installation results in a kernel warning "Trying to free already-free IRQ 0".

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.

2011-09-22sound: irq: Remove IRQF_DISABLEDYong Zhang4-5/+5
Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled], We run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled (see commit [b738a50a: genirq: Warn when handler enables interrupts]).

2011-09-14ALSA: mpu401: clean up interrupt specificationClemens Ladisch2-12/+11
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.
