rcar_i2c_probe() has priv->devtype operation, but handling (A) and (C) in same place is more understandable ( (A) 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> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Reviewed-by: Wolfram Sang <wsa+renesas@sang-engineering.com> --- v2 -> v3 - based on latest linux-next/master branch - add Reviewed-by from Wolfram drivers/i2c/busses/i2c-rcar.c | 12 +++++------- 1 file changed, 5 insertions(+), 7 deletions(-)
