A number of panel drivers track enabled/prepared state (I suspect to protect
regulator refcounts). However, the atomic framework already ensures that
prepare/unprepare and enable/disable calls are balanced. This series removes all
independent tracking from the drivers and adds a WARNING to the core in case
someone uses a panel with a legacy driver.
Changes in v2:
- Addressed review comments in first patch
- Since the initial set didn't get much action, this is a partial RESEND
Changes in v3:
- Fixed typo in docs
- Moved static inlines out of header
- Used helper function to make the state transition
- All panel driver patches are the same as v1
