From 8d705195a9a3cf3bd6a7a530b63e0e523f87189f Mon Sep 17 00:00:00 2001 From: Naftali Goldstein Date: Wed, 5 Sep 2018 08:06:07 +0300 Subject: [PATCH] mac80211: fix saving a few HE values [ Upstream commit 77cbbc35a49b75969d98edce9400beb21720aa39 ] After masking the he_oper_params, to get the requested values as integers one must rshift and not lshift. Fix that by using the le32_get_bits() macro.
