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.
