Subject: Re: [PATCH] staging/comedi: Fix undefined array subscript

This patch works but it's nasty to re-intialize "reg" inside both
if else statements.  Just do it once at the begining of the
function.

That means we would also delete the ininitialization from the if
side of the if else statement:

 	if (devpriv->model == VMK8061_MODEL) {
-		reg = VMK8061_DO_REG;
 		tx_buf[0] = VMK8061_CMD_RD_DO;

regards,
dan carpenter
