There are two additional lines to remove (plus the associated comment) from isp_xclk_init(), as your patch makes a loop now terminate with if (condition) continue;. Those two lines could be removed later, keeping them doesn't break anything.

Those > two lines could be removed later, keeping them doesn't break anything. I think it's fine to take it through the media tree as the series doesn't have any dependencies on this patch. It was merely attempting to get rid of stuff so that we could move closer to clkdev dealing with a clk_hw rather than a struct clk - but I never made it that far with the series. Maybe at a later date... :)

No merged platform supplies xclks via platform data. As we want to slightly change the clkdev interface, rather than fixing this unused code, remove it instead.
