Hi
Believe it reacted to the code below.
If raw_sample = 0 is the correct starting value, I am not sure. But
leaving it uninitialized, I think is the worst choice.
if (ret < 0)
goto out;
ret = ad_sd_read_reg(sigma_delta, AD_SD_REG_DATA,
DIV_ROUND_UP(chan->scan_type.realbits + chan->scan_type.shift, 8),
&raw_sample);
....
out:
....
sample = raw_sample >> chan->scan_type.shift;
Best regards
