Subject: Re: [PATCH 13/13] drivers/media/tuners/e4000.c: use macros for
 i2c_msg initialization

I found only 15 uses of I2C_MSG_OP, out of 653 uses of one of the three
macros.  Since I2C_MSG_OP has the complete set of flags, I think it should
be OK?

One of the uses, in drivers/media/i2c/adv7604.c, is as follows:

       struct i2c_msg msg[2] = { { client->addr, 0, 1, msgbuf0 },
                                 { client->addr, 0 | I2C_M_RD, len, msgbuf1 }

I'm not sure what was intended, but I guess the second structure is
supposed to only do a read?
