There may be a chance that reading from DAS1800_CONTROL_C is necessary
before reading from DAS1800_STATUS. If that is true then please discard
this patch.
Actually the driver has a bug here.
The analog input samples should be munged if the inputs are
configured for
bipolar mode.
I have a series almost ready that cleans up this driver and fixes the
bug.
Hi Hartley, can the bug fix be placed at the top of your patch series?
Thanks.
The bug has been there forever (even in the "out-of-tree" version from
comedi.org, where I have just fixed it). There have been patches applied
to reformat and remove the incorrect bits of code, including
a142785d7c9d ("Staging: comedi: das1800: fixed multiple brace coding
style issues and pointer declaration style errors") and 82d28561b7e0
("staging: comedi: Remove if condition."). The latter patch,
82d28561b7e0, mainly served to hide the bug further!
