Current dapm widget has a single variable to describe its kcontrol's
type. As there can be many kcontrols in one widget it is inherently
presumed that the types are the same.
Lately there has been use cases where different types of kcontrols would
be needed for a single widget. Thus add pointer to dapm widget to hold
an array for different kcontrol types and modify the kcontrol creation
to operate in a loop based on individual kcontrol type.
Change control creation and deletion to use individual kcontrol types in
SOF driver. This is done in the same patch for not breaking bisect. SOF
driver is also currently the only one using the dapm widget
kcontrol_type.

Hi,
This is a patch for enabling multiple different types of kcontrols for
a dapm widget. It refactors the dapm kcontrol parsing by lifting the
creation loop and memory allocation up one level and making the type
variable to hold multiple type values. Sof driver is modified to use
this type information in the same patch as it is quite cumbersome to
split the changes nicely.
changes since v5:
- remove extra free reported by coccinelle (alloc was changed to devm_kcalloc)
changes since v4:
- change title from dapm -> topology
- remove cover letter
- cc maintainers, me learning list behavior, apologies for the noise
changes since v3:
- fix sparse warnings for not using le32_to_cpu
changes since v2:
- only 1 patch for not breaking bisect
- sof internal reviews -> minor changes + reviewed by tags
- no upstream comments after v2 -> assuming I'm on the right track here
Changes since v1:
- don't add kcontrol type to core i.e. to kcontrol and kcontrol_news
- extend existing dapm widget kcontrol_type into holding an array of
types
