From: Larry Finger Date: Sat, 14 May 2011 15:15:17 +0000 (-0500) Subject: rtlwifi: rtl8192c-common: rtl8192ce: Fix for HT40 regression X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=099fb8ab1e57e5d609ac686cc0ab6d1835a79155;p=openwrt%2Fstaging%2Fblogic.git rtlwifi: rtl8192c-common: rtl8192ce: Fix for HT40 regression The changes that were made to rtl8192ce when rtl8192cu was added broke HT40. The errors included a typo in rtlwifi, a missing routine in rtl8192ce and a missing callback of that routine in rtl8192c-common. This patch fixes the regression reported in Bug #35082.
