Work around by polling the CONFA register once a second
and restore all coeffcients and registers when CONFA
changes unexpectedly.

VMID Divider Enable and Select is controlled by BIT[2:1] of WM9081_VMID_CONTROL

This initial conversion just moves the register init, regulator acquisition
and device verification out to the I2C probe(). Movement of other parts of
the driver like the GPIO and beep generation code will follow.

Now that the WM8996 driver is using the regmap API for register I/O we no
longer need the ASoC card to be active in order to interact with the chip.
In order to be more idiomatic for Linux move most of the existing probe()
function out into the I2C probe() function prior to registration with ASoC.
The IRQ and GPIO init will be moved separately as these are slightly more
involved.

Allow drivers to optimise out the register cache sync if they didn't need
to do one. If the hardware is desynced from the register cache (by power
loss for example) then the driver should call regcache_mark_dirty() to
let the core know about this.

.. with new name. Because nothing says "really solid kernel release"
like naming it after an extinct animal that just happened to be in the
news lately.
Mountpoint crossing is similar to following procfs symlinks - we do
not get ->d_revalidate() called for dentry we have arrived at, with
unpleasant consequences for NFS4.
Simple way to reproduce the problem in mainline:
cat >/tmp/a.c <<'EOF'
#include <unistd.h>
#include <fcntl.h>
#include <stdio.h>
main()
{
struct flock fl = {.l_type = F_RDLCK, .l_whence = SEEK_SET, .l_len = 1};
if (fcntl(0, F_SETLK, &fl))
perror("setlk");
}
EOF
cc /tmp/a.c -o /tmp/test
then on nfs4:
mount --bind file1 file2
/tmp/test < file1 # ok
/tmp/test < file2 # spews "setlk: No locks available"...
What happens is the missing call of ->d_revalidate() after mountpoint
crossing and that's where NFS4 would issue OPEN request to server.
The fix is simple - treat mountpoint crossing the same way we deal with
following procfs-style symlinks. I.e. set LOOKUP_JUMPED...
