I 'think' this bug could cause actual trouble but I'll assume it is relatively unlikely
and have applied this to the togreg branch of iio.git (won't apply to the current fixes
branch).

Anyhow, applied to the togreg branch of iio.git

Applied to the togreg branch of iio.git

Anyone fancy getting this driver into a clean form and proposing taking
it out of staging?

Does anyone know what still needs to be done in order to take it out of staging?

I think it should have been taken out of staging for a while now ;-)

Post a patch moving it with full code (turn off the move stuff in git format patch) and see what reviews you get.

Obviously best if someone who knows the driver does an initial pass for any cleanups code simplifications and stuff like missing docs.

Will it not be better to get Jurgens' patches in first ?

Ok, then I will send a patch moving the mxs-lradc driver into
drivers/iio after Juergen's patches get applied.
