Subject: wireless: fix warnings from QoS patch
X-Git-Tag: v2.6.27-rc1~969^2~112
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0b57664cf2393bc1eff594ff7e5ff26533843fe6;p=linux-2.6

wireless: fix warnings from QoS patch

When I removed the special "default" meaning from the QoS
parameters, I forgot to update drivers and this lead to
warnings because some drivers were checking for the special
values and putting in defaults. This fixes that by removing
the default special-casing completely.
