I was wrong. Correct is set_fan_div().
static ssize_t set_fan_div (struct i2c_client *client, struct fscher_data
*data, const char *buf, size_t count, int nr, int reg)
{
/* supported values: 2, 4, 8 */
int v = simple_strtoul(buf, NULL, 10);
switch (v)
{
case 2: v = 1; break;
case 4: v = 2; break;
case 8: v = 3; break;
default: return -1;
}
/* bits 2..7 reserved => mask with 0x03 */
data->fan_ripple[FAN_INDEX_FROM_NUM(nr)] &= ~0x03;
data->fan_ripple[FAN_INDEX_FROM_NUM(nr)] |= v;
fscher_write_value(client, reg, data->fan_ripple[FAN_INDEX_FROM_NUM(nr)]);
return count;
}
Bye.
