((thermometer < 0) ? 0 : (thermometer == X)) and (thermometer == X) are equal for X >= 0.X is not guaranteed to be >= 0 hereX is fixed constant. In this case X is {0, 1, 2}.
Looks like it can be -1 to me (range: -1, 0, 1, 2)
static int ar9003_hw_get_thermometer(struct ath_hw *ah)
{
struct ar9300_eeprom *eep = &ah->eeprom.ar9300_eep;
struct ar9300_base_eep_hdr *pBase = &eep->baseEepHeader;
int thermometer = (pBase->miscConfiguration >> 1) & 0x3;
return --thermometer;
