@ -450,22 +450,20 @@ continuous like for example a tempX_type, then when an invalid value is
written, -EINVAL should be returned.
Example1, temp1_max, register is a signed 8 bit value (-128 - 127 degrees):
--- begin code ---
long v = simple_strtol(buf, NULL, 10) / 1000;
SENSORS_LIMIT(v, -128, 127);
/* write v to register */
--- end code ---
long v = simple_strtol(buf, NULL, 10) / 1000;
v = SENSORS_LIMIT(v, -128, 127);
/* write v to register */
Example2, fan divider setting, valid values 2, 4 and 8:
--- begin code ---
unsigned long 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 -EINVAL;
}
/* write v to register */
--- end code ---
unsigned long 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 -EINVAL;
}
/* write v to register */
