Format specifier %p can leak kernel addresses while not valuing the
kptr_restrict system settings. When kptr_restrict is set to (1), kernel
pointers printed using the %pK format specifier will be replaced with 0's.
So that %pK will not leak kernel pointers to unprivileged users.
So change the format specifier from %p to %pK.
Debugging Note : &pK prints only Zeros as address. if you need actual
address information, pls echo 0 to kptr_restrict.
$ echo 0 > /proc/sys/kernel/kptr_restrict

The array index value when setting/getting the channels
of proxy is incorrect as the channel count begins from two.
Fix by setting the correct index offset.

Registers for page 0x50 in the wcd934x audio codec are currently
not defined. These registers control WCD DSP register configuration
and setup. Add these register definitions so that codec driver can
read/write these registers.

DAPM marks back end dai as dirty during ASoC suspend
which triggers device path teardown. Add ignore suspend
to all back end dais to avoid device path teardown.

In general, the IOMMU framework likes to group PCI devices together.
This prevents someone from assigning them to separate VMs using VFIO,
for example. The reason they shouldn't go to separate VMs is because
there could be DMA aliasing between endpoint devices, and because the
root complex device can access anything that endpoint devices can
access.
Unfortunately, this makes things difficult in the DMA layer since the
IOMMU framework freaks out if you try to attach a single device that is
also part of a group. First instinct might be to start using
iommu_attach_group instead of iommu_attach_device in the DMA layer but
that has problems of its own (it attaches *everyone* in the group as
soon as one client attaches). Besides all that, it's also a bit
annoying to have the root complex device in group since, in our
platform, it doesn't actually have any stream IDs assigned to it and it
doesn't do any DMA of its own, so it doesn't really make any logical
sense to attach it.
As a compromise, we can stop grouping PCI devices together by allocating
a new domain for each one. By doing so we no longer need to call
iommu_attach_group in the DMA layer, avoid the issues described above.
It should be noted that with this patch in place we can't securely do
any direct DMA assignment of PCI endpoint devices to separate VMs.
