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/tda18271-common.c | 15 +++++---------- 1 file changed, 5 insertions(+), 10 deletions(-) diff --git a/drivers/media/tuners/tda18271-common.c b/drivers/media/tuners/tda18271-common.c index 221171e..d05ed53 100644 --- a/drivers/media/tuners/tda18271-common.c +++ b/drivers/media/tuners/tda18271-common.c @@ -125,10 +125,8 @@ int tda18271_read_regs(struct dvb_frontend *fe) unsigned char buf = 0x00; int ret; struct i2c_msg msg[] = { - { .addr = priv->i2c_props.addr, .flags = 0, - .buf = &buf, .len = 1 }, - { .addr = priv->i2c_props.addr, .flags = I2C_M_RD, - .buf = regs, .len = 16 } + I2C_MSG_WRITE(priv->i2c_props.addr, &buf, sizeof(buf)), + I2C_MSG_READ(priv->i2c_props.addr, regs, 16) }; tda18271_i2c_gate_ctrl(fe, 1); @@ -155,10 +153,8 @@ int tda18271_read_extended(struct dvb_frontend *fe) unsigned char buf = 0x00; int ret, i; struct i2c_msg msg[] = { - { .addr = priv->i2c_props.addr, .flags = 0, - .buf = &buf, .len = 1 }, - { .addr = priv->i2c_props.addr, .flags = I2C_M_RD, - .buf = regdump, .len = TDA18271_NUM_REGS } + I2C_MSG_WRITE(priv->i2c_props.addr, &buf, sizeof(buf)), + I2C_MSG_READ(priv->i2c_props.addr, regdump, sizeof(regdump)) }; tda18271_i2c_gate_ctrl(fe, 1); @@ -192,8 +188,7 @@ int tda18271_write_regs(struct dvb_frontend *fe, int idx, int len) struct tda18271_priv *priv = fe->tuner_priv; unsigned char *regs = priv->tda18271_regs; unsigned char buf[TDA18271_NUM_REGS + 1]; - struct i2c_msg msg = { .addr = priv->i2c_props.addr, .flags = 0, - .buf = buf }; + struct i2c_msg msg = I2C_MSG_WRITE(priv->i2c_props.addr, buf, 0); int i, ret = 1, max; BUG_ON((len == 0) || (idx + len > sizeof(buf))); -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
