But I still alway get this error message when set DB8500_THERMAL, include/linux/mfd/dbx500-prcmu.h:459:19: error: redefinition of ‘prcmu_abb_read’ include/linux/mfd/db8500-prcmu.h:673:19: note: previous definition of ‘prcmu_abb_read’ was here include/linux/mfd/dbx500-prcmu.h:464:19: error: redefinition of ‘prcmu_abb_write’ include/linux/mfd/db8500-prcmu.h:678:19: note: previous definition of ‘prcmu_abb_write’ was here include/linux/mfd/dbx500-prcmu.h:475:19: error: redefinition of ‘prcmu_config_clkout’ include/linux/mfd/db8500-prcmu.h:643:19: note: previous definition of ‘prcmu_config_clkout’ was here include/linux/mfd/dbx500-prcmu.h:537:19: error: redefinition of ‘prcmu_ac_wake_req’ include/linux/mfd/db8500-prcmu.h:683:19: note: previous definition of ‘prcmu_ac_wake_req’ was here include/linux/mfd/dbx500-prcmu.h:542:20: error: redefinition of ‘prcmu_ac_sleep_req’ include/linux/mfd/db8500-prcmu.h:688:20: note: previous definition of ‘prcmu_ac_sleep_req’ was here $ grep prcmu_abb_read include/linux/mfd/* include/linux/mfd/db8500-prcmu.h:int prcmu_abb_read(u8 slave, u8 reg, u8 *value, u8 size); include/linux/mfd/db8500-prcmu.h:static inline int prcmu_abb_read(u8 slave, u8 reg, u8 *value, u8 size) include/linux/mfd/dbx500-prcmu.h:int prcmu_abb_read(u8 slave, u8 reg, u8 *value, u8 size); include/linux/mfd/dbx500-prcmu.h:static inline int prcmu_abb_read(u8 slave, u8 reg, u8 *value, u8 size) this functions are defined in both db8500-prmcu.h and dbx500-prcmu.h, plus linux/mfd/dbx500-prcmu.h includes linux/mfd/db8500-prcmu.h. I do not know how it works before, but this is a bug to me. thanks, rui -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
