Subject: [ATM] br2684: Use seq_list_xxx helpers
X-Git-Tag: v2.6.23-rc1~1109^2~34
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9af97186fcc9a1d9bbf195eb4bc2399d0dd66223;p=linux-2.6

[ATM] br2684: Use seq_list_xxx helpers

The .show callback receives the list_head pointer now, not the struct
br2684_dev one.
