i2c: rcar: make rcar_i2c_prepare_msg() *void*
rcar_i2c_prepare_msg() always returns 0, so we can make this function return *void* and thus remove the result check in rcar_i2c_master_xfer(). Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
