Subject: iwlwifi: mvm: make nd_ies part of the mvm struct
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=cc4c1ab5d22b22b945141edcbb74d0ab8caecbad;p=linux-beck.git

iwlwifi: mvm: make nd_ies part of the mvm struct

Instead of allocating nd_ies separately, make it part of the iwl_mvm
structure so it's easier to handle its lifetime.
