I've out-of-tree re-compiled the module with the patch applied, booted
into the kernel with secure boot / validation switched off, removed the
compiled-in module and did an insmod for the patched one.  It works and
I can read all values again most of the time at oversampling=1 and
consistently at oversampling=2 for all channels.

I'll try my suggestion of a tapered wait later, perhaps over the
weekend, now that I don't need to reboot to play around with the module
code.

Setting oversampling=1 on all three channels gets me a fuil acquisition
at ~33ms now (was ~28ms with the too short wait time), oversampling=2 is
at ~64ms.  I'll need to figure out how to enable and use the triggered
buffer to get that back to more reasonable times.


Regards,
Achim.
