Is cpu device special? Or why it is only one device which has=20 modalias file but is missing MODALIAS=3D line in uevent file? What userspace application should use for reading modalias=20 string? File modalias or file uevent? =2D-=20 Pali Roh=C3=A1r pali.rohar@gmail.com --nextPart2712852.Yg3XtZvm05 Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iEYEABECAAYFAlR3gwcACgkQi/DJPQPkQ1KfUQCffXtrteNro/ZhSM6pHM7aLqmW gbAAn3Kqb6MC+wIhD83UNC6AgY8zHSkp =NwAr -----END PGP SIGNATURE----- --nextPart2712852.Yg3XtZvm05--
