dmaengine: edma: Rename set_bits and remove unused clear_bits helper
The clear_bits() helper is not used by the driver so it can be removed. powerpc architecture defines the set_bits() in arch/powerpc/include/asm/bitops.h which results failed compile testing on powerpc architecture: >> drivers/dma/edma.c:415:20: error: conflicting types for 'set_bits' static inline void set_bits(int offset, int len, unsigned long *p) ^~~~~~~~ In file included from include/linux/bitops.h:36:0, from include/linux/kernel.h:10, from include/linux/list.h:8, from include/linux/kobject.h:20, from include/linux/device.h:17, from include/linux/dmaengine.h:20, from drivers/dma/edma.c:16: arch/powerpc/include/asm/bitops.h:75:14: note: previous definition of 'set_bits' was here DEFINE_BITOP(set_bits, or, "") ^ arch/powerpc/include/asm/bitops.h:58:24: note: in definition of macro 'DEFINE_BITOP' static __inline__ void fn(unsigned long mask, \ ^~ >> drivers/dma/edma.c:421:20: error: conflicting types for 'clear_bits' static inline void clear_bits(int offset, int len, unsigned long *p) ^~~~~~~~~~ In file included from include/linux/bitops.h:36:0, from include/linux/kernel.h:10, from include/linux/list.h:8, from include/linux/kobject.h:20, from include/linux/device.h:17, from include/linux/dmaengine.h:20, from drivers/dma/edma.c:16: arch/powerpc/include/asm/bitops.h:76:14: note: previous definition of 'clear_bits' was here DEFINE_BITOP(clear_bits, andc, "") ^ arch/powerpc/include/asm/bitops.h:58:24: note: in definition of macro 'DEFINE_BITOP' static __inline__ void fn(unsigned long mask, \ ^~ Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
