A commonly seen pattern is to run snd_ctl_find_id() for a mixer control element with a given string. Let's provide a standard helper for achieving that for simplifying the code. Link: https://lore.kernel.org/r/20230720082108.31346-2-tiwai@suse.deSigned-off-by:

ALSA: Make control API taking controls_rwsem consistently A few ALSA control API helpers like snd_ctl_rename(), snd_ctl_remove() and snd_ctl_find_*() suppose the callers taking card->controls_rwsem. But it's error-prone and fragile. This patch set tries to change those API functions to take the card->controls>rwsem internally by themselves, so that the drivers don't need to take care of lockings. After applying this patch set, only a couple of places still touch card->controls_rwsem (which are OK-ish as they need for traversing the control linked list).

Now that snd_ctl_find_id() takes the locking itself, we can get rid of the messy locking in the caller side in snd_emu10k1_verify_controls(). Link: https://lore.kernel.org/r/20230718141304.1032-12-tiwai@suse.deSigned-off-by:

Now all needed callers have been replaced with *_locked() versions, let's turn on the locking in snd_ctl_find_id() and snd_ctl_find_numid(). This patch also adds the lockdep assertions for debugging, too. Link: https://lore.kernel.org/r/20230718141304.1032-11-tiwai@suse.deSigned-off-by:

For reducing the unnecessary use of controls_rwsem in the drivers, this patch adds a new variant for snd_ctl_find_*() helpers: snd_ctl_find_id_locked() and snd_ctl_find_numid_locked() look for a kctl element inside the card->controls_rwsem -- that is, doing the very same as what snd_ctl_find_id() and snd_ctl_find_numid() did until now. snd_ctl_find_id() and snd_ctl_find_numid() remain same, i.e. still unlocked version, but they will be switched to locked version once after all callers are replaced. The patch also replaces the calls of snd_ctl_find_id() and snd_ctl_find_numid() in a few places; all of those are places where we know that the functions are called properly with controls_rwsem held. All others are without rwsem (although they should have been). After this patch, we'll turn on the locking in snd_ctl_find_id() and snd_ctl_find_numid() to be more race-free.

The controls_rwsem of snd_card object is rather an internal lock, and not really meant to be used by others for its data protection. This patch addresses it by replacing the controls_rwsem usages with the own (new) mutex. Note that the up_write() and down_write() calls around gbaudio_remove_component_controls() are simply dropped without replacement. These temporary up/down were a workaround since gbaudio_remove_component_controls() itself took the rwsem. Now it was also gone, we can clean up the workaround, too. Acked-by:

So far, snd_ctl_remove() requires its caller to take card->controls_rwsem manually before the call for avoiding possible races. However, many callers don't care and miss the locking. Basically it's cumbersome and error-prone to enforce it to each caller. Moreover, card->controls_rwsem is a field that should be used only by internal or proper helpers, and it's not to be touched at random external places. This patch is an attempt to make those calls more consistent: now snd_ctl_remove() takes the card->controls_rwsem internally, just like other API functions for kctls. Since a few callers already take the controls_rwsem locks, the patch removes those locks at the same time, too. Link: https://lore.kernel.org/r/20230718141304.1032-5-tiwai@suse.deSigned-off-by:

snd_ctl_rename() expects that card->controls_rwsem is held in the caller side for avoiding possible races, but actually no one really did that. It's likely because this operation is done usually only at the device initialization where no race can happen. But, it's still safer to take a lock, so we just take the lock inside snd_ctl_rename() like most of other API functions do.

Use PCI device IDs from pci_ids.h header. BSW replaces CHV, as 0x22a8 was added in PCI header as BSW ID for consistency, as they are same (similar) platforms. The ACPI IDs are used only internally and lower 16 bits uniquely define the device as vendor ID for Intel is 8086 for all of them. Use PCI_DEVICE_DATA() to match PCI device to be consistent with other Intel audio drivers. Suggested-by:

Given that the filter is already set to neutral for PCM voices, the only observable effect is that the Z1/Z2/FXBUS registers don't have a stray bit set for negative numbers anymore. The bit is below the ones significant for output, but it would mess with 32-bit sample recombination, which we intend to add. kX-project does that, but I had to figure out myself why. Signed-off-by:

85;95;0c This uses IRQs to track spontaneous changes to the word clock source register. FWIW, that this can happen in the first place is the reason why it is futile to lock the clock source mixer setting while the device is open - we can't consistently control the rate anyway. Though arguably, we should reset any open streams when that happens, as they become corrupted anyway. Signed-off-by:
