I confrm patch works on my "TUF GAMING Z490-PLUS (WI-FI)".

I also noticed that some voltage values reported by nct6775 differs from the
ones reported by Asus software on Windows.

I changed voltage scaling factors to those listed below and now voltages are
reported like on Asus software on Windows.

/*
 * Some of the voltage inputs have internal scaling, the tables below
 * contain 8 (the ADC LSB in mV) * scaling factor * 100
 */
static const u16 scale_in[15] = {
        888, 4000, 1600, 1600, 9600, 800, 800, 1600, 1600, 1600, 1600, 1600,
800,
        800, 800
};
