From: Jes Sorensen Date: Fri, 9 May 2014 13:03:18 +0000 (+0200) Subject: staging: rtl8723au: Fix endian abnormality in mlme_evt_hdl23a() X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0f6df02ad85fa79e48468932a9d93605a4088ba2;p=openwrt%2Fstaging%2Fblogic.git staging: rtl8723au: Fix endian abnormality in mlme_evt_hdl23a() Every other place uses C2HEvent_Header() for events. Given the struct is endian dependant, use it here too to retrieve data from the parm buffer. Note the length field is not set/read in le order - question is whether it's simply an opaque field?
