Per the other mail we will never hit this case.
So you add an ifdef that never will be used,
because this driver is either for IMX (which uses COMMON_CLK) or PowerPC.
There is this snip from the driver:
#ifdef CONFIG_COMMON_CLK
i2c_fsl->clk = clk_get(pdev, NULL);
if (IS_ERR(i2c_fsl->clk))
return PTR_ERR(i2c_fsl->clk);
#endif
You may have been inspired by that.
To the best of my understanding the ifdef can be dropped,
because clk_dev() is always defined, but retinr NULL if
HAVE_CLK is not defined.
I assume thsi is the case for PowerPC.
So the better fix would be to get rid of this ifdet,
rather than introducing a new one.
