This patch converts the resource management in PCI lx6464es 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/20210715075941.23332-42-tiwai@suse.de Signed-off-by:

This patch is an attempt to slightly simplify the resource management in HD-audio code, by using some device-managed APIs. Only a few resources like PCI enablement and PCI resources managed via devres, but most of the rest code dealing with HD-audio core stuff couldn't be changed so much, hence the changes in this patch are pretty small in the end. A special caveat is needed for the card object: we can't move the card object release into devres, because the driver is involved with the component stuff and its unregistiration doesn't work well from devres release at all.

Like the previous patch, this patch converts the resource allocations with device-managed API calls, so that we can reduce resource-free calls. The atiixp drivers are simpler than intel8x0, and even the irq can be allocated with devres. The end result is a good amount of code reduction.

This patch refactors the intel8x0 and intel8x0m driver codes using devres and gets rid of the driver remove callback. The conversion is fairly straightforward: each API call is replaced with the device-managed API function, e.g. pci_enable_device() -> pcim_enable_device(), and so on. The buffer descriptor list is allocated with a new API, snd_devm_alloc_pages(). A slight code structure change is that the intel8x0 object is allocated as a card's private_data instead of the own lowlevel snd_device object. This simplifies the resource management. And, the take-down procedure is triggered via card->private_free, and it's registered at the end of the whole initialization, i.e. after the all resources get properly managed. The only not-devres-managed resource is the irq handler. Since we need to release at suspend and re-acquire at resume (otherwise something weird happens on some machines), this is still managed manually. But the rest are all freed automatically. The end result is a good amount of code reduction. Link: https://lore.kernel.org/r/20210715075941.23332-6-tiwai@suse.de Signed-off-by:

This patch adds a devres-supported helper for requesting an ISA DMA channel that will be automatically freed at the device unbinding. It'll be used by quite a few ISA sound drivers. Link: https://lore.kernel.org/r/20210715075941.23332-4-tiwai@suse.de Signed-off-by:

As a second step for preliminary to widen the devres usages among sound drivers, this patch adds a new ALSA core API function, snd_devm_card_new(), to create a snd_card object via devres. When a card object is created by this new function, snd_card_free() is called automatically and the card object resource gets released at the device unbinding time. However, the story isn't that simple. A caveat is that we have to call snd_card_free() at the very first of the whole resource release procedure, in order to assure that the all exposed devices on user-space are deleted and sync with processes accessing those devices before releasing resources. For achieving it, snd_card_register() adds a new devres action to trigger snd_card_free() automatically when the given card object is a "managed" one. Since usually snd_card_register() is the last step of the initialization, this should work in most cases. With all these tricks, some drivers can get rid of the whole driver remove callback code. About a bit of implementation details: the patch adds two new flags to snd_card object: managed and releasing. The former indicates that the object was created via snd_devm_card_new(), and the latter is used for avoiding the double-free of snd_card_free() calls. Both flags are fairly internal and likely uninteresting to normal users. Link: https://lore.kernel.org/r/20210715075941.23332-3-tiwai@suse.de Signed-off-by:
