Well, I can own up to half a dozen inlines in a .c file, CodingStyle
suggests to convert macros to static inline, so I did:

/* adm9240 internally scales voltage measurements */
static const u16 nom_mv[] = { 2500, 2700, 3300, 5000, 12000, 2700 };

static inline unsigned int IN_FROM_REG(u8 reg, int n)
{
return SCALE(reg, nom_mv[n], 192);
}

static inline u8 IN_TO_REG(unsigned long val, int n)
{
return SENSORS_LIMIT(SCALE(val, 192, nom_mv[n]), 0, 255);
}

/* temperature range: -40..125, 127 disables temperature alarm */
static inline s8 TEMP_TO_REG(long val)
{
return SENSORS_LIMIT(SCALE(val, 1, 1000), -40, 127);
}

Are these typical targets for non-inline?

Thanks,
Grant.
