Johannes, Is it okay to use Patrick's second suggestion (use d->pll_init directly without bpll), as illustrated in the patch attached? I like this method best, as it does exactly as what I had originally intended. -Mike Signed-off-by: Michael Krufky <mkrufky@xxxxxxx> -------------- next part -------------- A non-text attachment was scrubbed...
