* clk: samsung: Properly include clk.h and clkdev.hStephen Boyd2015-07-201-2/+0Star
| | | | | | | | | | | | | | Clock provider drivers generally shouldn't include clk.h because it's the consumer API. Only include clk.h in files that are using it. The clkdev.h header isn't always used either, so remove it and add in slab.h where files were relying on it to include slab for them.
