I'd argue that
pd = (inbuf[0] >> 1) & 0x3;
if (pd) {
data->powerdown = true;
data->powerdown_mode = pd - 1;
} else {
data->powerdown = false;
data->powerdown_mode = 2; /* largest register to gnd */
}
is less compact but probably easier to read/understand;

but I'm fine with the proposed patch as well to make cocci happy
regards, p.

I agree, this is a much better fix. Would you like to submit this
version as a patch?

Applied to the togreg branch of iio.git and pushed out as testing
for the autobuilders to play with it.
Thanks,
