Then we should rather *fix* function usage *NOT* introduce an new function for the same job!
But wait an min, twl4030_i2c_[read|write]_u8 follows the same proto as twl6035_i2c_read/write_u8! You are welcome to fix both while at it. But please *DONOT* introduce duplicate functions on style need! -- Regards, Nishanth Menon _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
