Hello everyone. This is my first patch to linux kernel. Once I get the
hang of this process, I will be sending patches form GSoC 2023 greybus
driver. Feel free to tell me if I am doing something wrong here

2.41.0
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).

ALSA: control: Take card->controls_rwsem in snd_ctl_rename()
staging: greybus: audio_helper: Use snd_ctl_remove_id()
ASoC: atmel: mchp-pdmc: Use snd_ctl_remove_id()
ALSA: control: Take controls_rwsem lock in snd_ctl_remove()
ALSA: control: Add lockdep warning to internal functions
ASoC: sigmadsp: Simplify with snd_ctl_activate_id()
staging: greybus: Avoid abusing controls_rwsem
ALSA: control: Make snd_ctl_find_id() argument const
ALSA: control: Introduce unlocked version for snd_ctl_find_*() helpers
ALSA: control: Take lock in snd_ctl_find_id() and snd_ctl_find_numid()
ALSA: emu10k1: Go back and simplify with snd_ctl_find_id()
