[PATCH 00/14] Fix driver reload issues

[Amadeusz SÅawiÅski]

Hi,

This series of patches introduces fixes to various issues found while
trying to unload all snd* modules and then loading them again. This
allows for modules to be really _modules_ and be unloaded and loaded on
demand, making it easier to develop and test them without constant
system reboots.

There are some fixes in flow, either we don't initialize things before
cleaning them up, clean up in wrong places or don't clean up at all.
Other patches fix memory management problems, mostly things are not
being freed. And finally there is few miscellaneous patches, please
refer to specific patches to see what they do.

This series was tested on SKL, BXT, GLK & KBL.

Small note:
Patch 2 in this series was already send to this list along with SOF
counterpart, however it seems that there is some problem:
https://mailman.alsa-project.org/pipermail/alsa-devel/2019-May/149638.html
and related patch on SOF side (with discussion):
https://mailman.alsa-project.org/pipermail/alsa-devel/2019-May/149640.html
It is included in this patchset for completeness.
