Subject: dbus: Use simple strings for debug level
X-Git-Tag: hostap_0_7_1~61
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a2753c285fc0efc5f65138d8f95de1e903b0fa31;p=thirdparty%2Fhostap.git

dbus: Use simple strings for debug level

Instead of using some magic integer values that really only mean
something to WPA internal code, just use simple strings. Possible
values are "msgdump", "debug", "info", "warning" and "error" which
map directly to WPA debugging support.
