ALSA: riptide: Fix the missing snd_card_free() call at probe error

2022-04-12T15:58:31Z

The previous cleanup with devres may lead to the incorrect release orders at the probe error handling due to the devres's nature. Until we register the card, snd_card_free() has to be called at first for releasing the stuff properly when the driver tries to manage and release the stuff via card->private_free(). This patch fixes it by calling snd_card_free() on the error from the probe callback using a new helper function.

ALSA: riptide: Allocate resources with device-managed APIs

2021-07-19T14:17:05Z

This patch converts the resource management in PCI riptide 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/20210715075941.23332-45-tiwai@suse.de Signed-off-by: Takashi Iwai

ALSA: riptide: Fix assignment in if condition

2021-06-09T15:30:18Z

PCI riptide 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/20210608140540.17885-48-tiwai@suse.de Signed-off-by: Takashi Iwai

module: remove never implemented MODULE_SUPPORTED_DEVICE

2021-03-17T20:16:18Z

MODULE_SUPPORTED_DEVICE was added in pre-git era and never was implemented. We can safely remove it, because the kernel has grown to have many more reliable mechanisms to determine if device is supported or not. Signed-off-by: Leon Romanovsky Signed-off-by: Linus Torvalds

ALSA: riptide: Replace tasklet with threaded irq

2020-09-09T16:34:10Z

The tasklet is an old API that should be deprecated, usually can be converted to another decent API. In Riptide driver, a tasklet is still used for offloading the PCM IRQ handling. It can be achieved gracefully with a threaded IRQ, too. This patch replaces the tasklet usage in riptide driver with a threaded IRQ.

ALSA: riptide: convert tasklets to use new tasklet_setup() API

2020-09-02T11:25:15Z

In preparation for unconditionally passing the struct tasklet_struct pointer to all tasklet callbacks, switch to using the new tasklet_setup() and from_tasklet() to pass the tasklet pointer explicitly.

ALSA: riptide: More constifications

2020-01-05T15:14:40Z

Apply const prefix to each lbus path table definition and its callers. Just for minor optimization and no functional changes. Link: https://lore.kernel.org/r/20200105144823.29547-16-tiwai@suse.de Signed-off-by: Takashi Iwai

ALSA: pci: Constify snd_ac97_bus_ops definitions

2020-01-03T08:24:13Z

Now snd_ac97_bus() takes the const ops pointer, so we can define the snd_ac97_bus_ops locally as const as well for further optimization. There should be no functional changes by this patch. Link: https://lore.kernel.org/r/20200103081714.9560-28-tiwai@suse.de Signed-off-by: Takashi Iwai

ALSA: pci: Constify snd_device_ops definitions

2020-01-03T08:23:56Z

Now we may declare const for snd_device_ops definitions, so let's do it for optimization. There should be no functional changes by this patch. Link: https://lore.kernel.org/r/20200103081714.9560-10-tiwai@suse.de Signed-off-by: Takashi Iwai

ALSA: riptide: Support PCM sync_stop

2019-12-11T06:25:51Z

The driver invokes snd_pcm_period_elapsed() simply from the interrupt handler. Set card->sync_irq for enabling the missing sync_stop PCM operation. Link: https://lore.kernel.org/r/20191210063454.31603-31-tiwai@suse.de Signed-off-by: Takashi Iwai
