The return value of snd_hda_param_read() is -1 for an error, otherwise
it's the supported power states of a codec.
The supported power states is a 32-bit value. Bit 31 will be set to 1 if the
codec supports EPSS, thus making "sup" negative. And the bit 28:5 is reserved as "0".
So a negative value other than -1 shall be further checked.
Please refer to High-Definition spec 7.3.4.12 "Supported Power States",
thanks!

Could you resend in a normal text? It's garbled badly with HTML in the signature and can't be applied.
Also, try to shorten the subject a bit more.
thanks,
Takashi
