The WM8994 is a highly integrated ultra-low power hi-fi audio subsystem
designed for smartphones and other portable devices rich in multimedia
features. It provides advanced digital mixing facilities enabling low
power high quality interconnection of CPU, baseband and other audio
sources through flexible digital and analogue routing, and integrates
a class W headphone driver and stereo class D speaker drivers.

Perform DC servo offset calibration using a series update sequence
rather than startup update sequence, tuning the configuration of the
WM8993 DC servo to make best use of this.
Also introduce currently unused data allowing us to correct for
any systematic errors in the DC servo calibration results and an
alternative startup path for the headphone output which performs
better with some chip revisions. The alternative setup sequence is
enabled for WM8993.

In case, if OPCLK is not used, and PLL is used for driving the codec, the

wm8974 and wm8978 codec drivers control DAC and ADC oversampling rates in their

switches and not clock dividers. Move these bits to sound controls. Also remove

In free_unmap_area_noflush(), va->flags is marked as VM_LAZY_FREE first, and
then vmap_lazy_nr is increased atomically.
But, in __purge_vmap_area_lazy(), while traversing of vmap_are_list, nr
is counted by checking VM_LAZY_FREE is set to va->flags. After counting
the variable nr, kernel reads vmap_lazy_nr atomically and checks a
BUG_ON condition whether nr is greater than vmap_lazy_nr to prevent
vmap_lazy_nr from being negative.
The problem is that, if interrupted right after marking VM_LAZY_FREE,
increment of vmap_lazy_nr can be delayed. Consequently, BUG_ON
condition can be met because nr is counted more than vmap_lazy_nr.
It is highly probable when vmalloc/vfree are called frequently. This
scenario have been verified by adding delay between marking VM_LAZY_FREE
and increasing vmap_lazy_nr in free_unmap_area_noflush().
Even the vmap_lazy_nr is for checking high watermark, it never be the
strict watermark. Although the BUG_ON condition is to prevent
vmap_lazy_nr from being negative, vmap_lazy_nr is signed variable. So,
it could go down to negative value temporarily.
Consequently, removing the BUG_ON condition is proper.
A possible BUG_ON message is like the below.
