Why are you exporting these functions if no one calls them?
They are used in the next series, see '[RFC PATCH 04/12] ASoC: SOF: Intel:
add SoundWire configuration interface'
That wasn't obvious :)
Also, why not EXPORT_SYMBOL_GPL()? :)
Since the beginning of this SoundWire work, the intent what that the
code could be reused in non-GPL open-source circles, hence the dual
license and EXPORT_SYMBOL.
That said, there are cases where the code only makes sense for Linux, or
relies on symbols that are exported with EXPORT_SYMBOL_GPL, in those
cases we rely on GPLv2 and EXPORT_SYMBOL_GPL. For this series I added a
disclaimer in the cover letter that those parts need to be reviewed
further to make sure there are no conflicts with GPL.
This is an RFC-level contribution to check if my understanding of the
bus/device/driver model is aligned with recommendations. I've already
made local improvements by fixing bisect issues, removing warnings,
improved some sequences, and that GPL question will be revisited before
I send a formal patch.
