[linux-dvb] mdelay(10) ves1820_writereg()

Hi!

Is there some good reason why there is mdelay(10) in ves1820_writereg():

static int ves1820_writereg(struct ves1820_state *state, u8 reg, u8 data)
{
        u8 buf[] = { 0x00, reg, data };
        struct i2c_msg msg = {.addr = state->config->demod_address,.flags = 0,.buf = buf,.len = 3};
        int ret;

        ret = i2c_transfer(state->i2c, &msg, 1);

        if (ret != 1)
                printk("ves1820: %s(): writereg error (reg == 0x%02x,"
                        "val == 0x%02x, ret == %i)\n", __FUNCTION__, reg, data, ret);

        msleep(10);
        return (ret != 1) ? -EREMOTEIO : 0;
}

Doesn't it slow down lot of i2c communication?
