rcar_i2c_probe() has priv->devtype operation, but handling (A) and (C) in same place is more easy-to-understand ((A)(C) and (B) are independent). (A) if (priv->devtype < I2C_RCAR_GEN3) { ... } (B) ... (C) if (priv->devtype >= I2C_RCAR_GEN3) { ... } Let's merge it with if-else Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> --- drivers/i2c/busses/i2c-rcar.c | 10 ++++------ 1 file changed, 4 insertions(+), 6 deletions(-)
