Looking through the uses, many people don't care, so they declare a dummy or share one variable between several parameters. The latter is problematic because sysfs uses that number to decide how many to display. The solution is to change the variable arg to a pointer, and if the pointer is NULL, use the "max" value. This change is fairly small, but fixing up the callers is a lot of (trivial) churn.

It seems that the pci structure passed to our code is broken. The driver has had no changes in initialization for a long time." i hope these information will help a bit. thank you for your assistance, i really appreciate it Christian (still wondering why nobody else has this bug, 1370 is not *that* weird, i thought) PS: if someone could explain me, why the ChangeSet numbers are always different: i've used "bk revtool sound/pci/ens1370.c" to find out the changes for this file and the suspicious patch reads sound/pci/ens1370.c@1.54.1.1, 2004-10-20.... in "bk revtool". the changelog however reads: ChangeSet@1.2011, 2004-10-20 08:10:43-07:00, rusty@rustcorp.com.au - -- BOFH excuse #62: need to wrap system in aluminum foil to fix problem -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFBjkcE+A7rjkF8z0wRAkR/AJ98DKSv5dZfOSJdKGWdz1LWPlItgQCgvS1A iS1wUtTgHzsx4JFpqsQGt68= =Hv9R -----END PGP SIGNATURE-----
