2021-07-19ALSA: es1968: Allocate resources with device-managed APIsTakashi Iwai
This patch converts the resource management in PCI es1968 driver with devres as a clean up. Each manual resource management is converted with the corresponding devres helper, and the card object release is managed now via card->private_free instead of a lowlevel snd_device. This should give no user-visible functional changes. Link: https://lore.kernel.org/r/20210715075941.23332-19-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2021-06-09ALSA: es1968: Fix assignment in if conditionTakashi Iwai
PCI ES1968 driver code contains a few assignments in if condition, which is a bad coding style that may confuse readers and occasionally lead to bugs. This patch is merely for coding-style fixes, no functional changes. Link: https://lore.kernel.org/r/20210608140540.17885-27-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>

2014-10-30ALSA: es1968: Replace timeval with ktime_tTina Ruchandani
es1968_measure_clock uses struct timeval, which on 32-bit systems will overflow in 2038, leading to incorrect interpretation of time.This patch changes the function to use ktime_t instead of struct timeval, which implies: - no y2038: ktime_t uses a 64-bit datatype explicitly. - efficent subtraction: The earlier version computes the difference in usecs while dealing with secs and nsecs. It requires checks to see if the nsecs of stop is less than start. This patch uses a direct subtract of ktime_t and converts to usecs. - use of monotonic clock (ktime_get) over real time (do_gettimeofday), which simplifies timekeeping, as it does not have to deal with cases where stop_time is less than start_time.

2011-09-14ALSA: mpu401: clean up interrupt specificationClemens Ladisch
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 Iwai
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 Iwai
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>
