ce2d8ed8d8 ASoC: qcom: Convert to generic PCM copy ops
This patch converts the qcom lpass driver code to use the new unified
PCM copy callback.  It's a straightforward conversion from *_user() to
*_iter() variants.

Note that copy_from/to_iter() returns the copied bytes, hence the
error condition is adjusted accordingly.

95396d83e9 ASoC: mediatek: Convert to generic PCM copy ops
This patch converts the mediatek BT SCO driver code to use the new
unified PCM copy callback.  It's a straightforward conversion from
*_user() to *_iter() variants.  As copy_form/to_iter() updates the
internal offset at each read/write, we can drop the cur_*_idx counter
in the loop, too.

Note that copy_from/to_iter() returns the copied bytes, hence the
error condition is adjusted accordingly.

66201cacc3 ASoC: component: Add generic PCM copy ops
For following the ALSA PCM core change, a new PCM copy ops is added
toe ASoC component framework: snd_soc_component_driver receives the
copy ops, and snd_soc_pcm_component_copy() helper is provided.

This also fixes a long-standing potential bug where the ASoC driver
covers only copy_user PCM callback and misses the copy from kernel
pointers (such as OSS PCM layer), too.

As of this patch, the old copy_user is still kept, but it'll be
dropped later after all drivers are converted.

cf393babb3 ALSA: pcm: Add copy ops with iov_iter
iov_iter is a universal interface to copy the data chunk from/to
user-space and kernel in a unified manner.  This API can fit for ALSA
PCM copy ops, too; we had to split to copy_user and copy_kernel in the
past, and those can be unified to a single ops with iov_iter.

This patch adds a new PCM copy ops that passes iov_iter for copying
both kernel and user-space in the same way.  This patch touches only
the ALSA PCM core part, and the actual users will be replaced in the
following patches.

The expansion of iov_iter is done in the PCM core right before calling
each copy callback.  It's a bit suboptimal, but I took this now as
it's the most straightforward replacement.  The more conversion to
iov_iter in the caller side is a TODO for future.

As of now, the old copy_user and copy_kernel ops are still kept.
Once after all users are converted, we'll drop the old copy_user and
copy_kernel ops, too.

Simplify the code using gpiod_get_optional() and drop the
special "of" parsing function: these descriptors need not
come from device tree and it's optional so hey.

Keep some NULL checks around the GPIO operations even though
gpiolib is essentially NULL-tolerant, because by checking
for whether we have a valid GPIO descriptor or not we can
avoid a 400 ms delay which is great.

There is also a need to support instantiating this driver using software
nodes. This is for systems where the CS35L56 is a back-end device and the
ACPI refers only to the front-end audio device - there will not be any ACPI
references to CS35L56.

Align with the other components, and use snd_device_alloc() for the
new sound device for timer, too.  No functional changes.

b53a41ee9c ALSA: compress: Don't embed device
Embedding the struct device to snd_compr object may result in UAF when
the delayed kobj release is used.  Like other devices, let's detach
the struct device from the snd_compr by allocating dynamically via
snd_device_alloc().

ea29a02fd8 ALSA: rawmidi: Don't embed device
This patch detaches the struct device from the snd_rawmidi object by
allocating via snd_device_alloc(), just like done for other devices.

897c8882df ALSA: hwdep: Don't embed device
Like control and PCM devices, it's better to avoid the embedded struct
device for hwdep (although it's more or less well working), too.
Change it to allocate via snd_device_alloc(), and free the memory at
the common snd_hwdep_free().

bc41a7228c ALSA: pcm: Don't embed device
So far we use the embedded struct device for each PCM substreams in
struct snd_pcm.  This may result in UAF when the delayed kobj release
is used; each corresponding struct device is still accessed at the
(delayed) device release, while the snd_pcm object may be already
gone.

As a workaround, detach the struct device from the snd_pcm object by
allocating via the new snd_device_alloc() helper.

A caveat is that we store the PCM substream pointer to drvdata since
the device resume and others require the access to it.

This patch is based on the fix Curtis posted initially.  In this
patch, the changes are split and use the new helper function instead.

6a66b01de4 ALSA: control: Don't embed ctl_dev
Embedding the ctl_dev in the snd_card object may result in UAF when
the delayed kobj release is used; at the delayed kobj release, it
still accesses the struct device itself while the card memory (that
embeds the struct device) may be already gone.

As a workaround, detach the struct device from the card object by
allocating via the new snd_device_alloc() helper.  The rest are just
replacing ctl_dev access to the pointer.

This is based on the fix Curtis posted initially.  In this patch, the
changes are split and use the new helper function instead.
