From: Julia Lawall <Julia.Lawall@xxxxxxx> Introduce use of I2c_MSG_READ/WRITE/OP, for readability. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression a,b,c; identifier x; @@ struct i2c_msg x = - {.addr = a, .buf = b, .len = c, .flags = I2C_M_RD} + I2C_MSG_READ(a,b,c) ; @@ expression a,b,c; identifier x; @@ struct i2c_msg x = - {.addr = a, .buf = b, .len = c, .flags = 0} + I2C_MSG_WRITE(a,b,c) ; @@ expression a,b,c,d; identifier x; @@ struct i2c_msg x = - {.addr = a, .buf = b, .len = c, .flags = d} + I2C_MSG_OP(a,b,c,d) ; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx> --- drivers/media/tuners/tda18218.c | 19 +++---------------- 1 file changed, 3 insertions(+), 16 deletions(-) diff --git a/drivers/media/tuners/tda18218.c b/drivers/media/tuners/tda18218.c index 1819853..c0c2fef 100644 --- a/drivers/media/tuners/tda18218.c +++ b/drivers/media/tuners/tda18218.c @@ -26,11 +26,7 @@ static int tda18218_wr_regs(struct tda18218_priv *priv, u8 reg, u8 *val, u8 len) int ret = 0, len2, remaining; u8 buf[1 + len]; struct i2c_msg msg[1] = { - { - .addr = priv->cfg->i2c_address, - .flags = 0, - .buf = buf, - } + I2C_MSG_WRITE(priv->cfg->i2c_address, buf, 0) }; for (remaining = len; remaining > 0; @@ -65,17 +61,8 @@ static int tda18218_rd_regs(struct tda18218_priv *priv, u8 reg, u8 *val, u8 len) int ret; u8 buf[reg+len]; /* we must start read always from reg 0x00 */ struct i2c_msg msg[2] = { - { - .addr = priv->cfg->i2c_address, - .flags = 0, - .len = 1, - .buf = "\x00", - }, { - .addr = priv->cfg->i2c_address, - .flags = I2C_M_RD, - .len = sizeof(buf), - .buf = buf, - } + I2C_MSG_WRITE(priv->cfg->i2c_address, "\x00", 1), + I2C_MSG_READ(priv->cfg->i2c_address, buf, sizeof(buf)) }; ret = i2c_transfer(priv->i2c, msg, 2); -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
