There are several things the patch adding the support for 'I2S Reference'
got wrong:
- "None" selection is in fact equals to last selected reference
- The custom put overrides RX/TX len, TDM slot sizes, etc
- the enum is useless in most part for the reference tracking
- there is no need for EXT control as there is a single bit in
RT1011_TDM1_SET_1 register (bit 7) which selects the reference
- it was using ucontrol->value.integer.value[0] in the put/get callbacks

The tmp[] member of the gpiochip_fwd structure is used to store both the
temporary values bitmap and the desc pointers for operations on multiple
GPIOs. As both are arrays with sizes unknown at compile-time, accessing
them requires offset calculations, which are currently duplicated in
gpio_fwd_get_multiple() and gpio_fwd_set_multiple().
Introduce (a) accessors for both arrays and (b) a macro to calculate the
needed storage size. This confines the layout of the tmp[] member into
a single spot, to ease maintenance.

Some NVMEM providers have certain nvmem cells encoded, which requires
post processing before actually using it.
For example mac-address is stored in either in ascii or delimited or reverse-order.
Having a post-process callback hook to provider drivers would enable them to
do this vendor specific post processing before nvmem consumers see it.

In the existing design, we do not create a instance per nvmem cell consumer
but we directly refer cell from nvmem cell list that are added to provider.
However this design has some limitations when consumers want to assign name
or connection id the nvmem cell instance, ex: via "nvmem-cell-names" or
id in nvmem_cell_get(id).
Having a name associated with nvmem cell consumer instance will help
provider drivers in performing post processing of nvmem cell data if required
before data is seen by the consumers. This is pretty normal with some vendors
storing nvmem cells like mac-address in a vendor specific data layouts that
are not directly usable by the consumer drivers.
With this patch nvmem cell will be created dynamically during nvmem_cell_get
and destroyed in nvmem_cell_put, allowing consumers to associate name with
nvmem cell consumer instance.
With this patch a new struct nvmem_cell_entry replaces struct nvmem_cell
for storing nvmem cell information within the core.
This patch does not change nvmem-consumer interface based on nvmem_cell.

*p &= GENMASK((cell->nbits%BITS_PER_BYTE) - 1, 0);

subtract one from that making a large number that is then shifted more than the

If drm_modeset_lock() returns -EDEADLK, the caller is supposed to drop
all currently held locks using drm_modeset_backoff(). Failing to do so
will result in warnings and backtraces on the paths trying to lock a
contended lock. Add support for optionally printing the backtrace on the
path that hit the deadlock and didn't gracefully handle the situation.
For example, the patch [1] inadvertently dropped the return value check
and error return on replacing calc_watermark_data() with
intel_compute_global_watermarks(). The backtraces on the subsequent
locking paths hitting WARN_ON(ctx->contended) were unhelpful, but adding
the backtrace to the deadlock path produced this helpful printout:

SRAM driver often returns -EPROBE_DEFER and thus this bus driver often
prints error message, even if it probes successfully later. This is
confusing for users and they often think that something is wrong.
Use dev_err_probe() helper for printing error message. It handles
-EPROBE_DEFER automatically.

Up to now ad_dpot_remove() returns zero unconditionally. Make it return
void instead which makes it easier to see in the callers that there is
no error to handle.
Also the return value of i2c and spi remove callbacks is ignored anyway.

It turns out that access to config space before completing the feature
negotiation is broken for big endian guests at least with QEMU hosts up
to 6.1 inclusive. This affects any device that accesses config space in
the validate callback: at the moment that is virtio-net with
VIRTIO_NET_F_MTU but since 82e89ea077 ("virtio-blk: Add validation for
block size in config space") that also started affecting virtio-blk with
VIRTIO_BLK_F_BLK_SIZE. Further, unlike VIRTIO_NET_F_MTU which is off by
default on QEMU, VIRTIO_BLK_F_BLK_SIZE is on by default, which resulted
in lots of people not being able to boot VMs on BE.
The spec is very clear that what we are doing is legal so QEMU needs to
be fixed, but given it's been broken for so many years and no one
noticed, we need to give QEMU a bit more time before applying this.
Further, this patch is incomplete (does not check blk size is a power
of two) and it duplicates the logic from nbd.
Revert for now, and we'll reapply a cleaner logic in the next release.
