Subject: iwlwifi: mvm: update power after phy_ctxt is NULL when unassigning chanctx
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3b0077226733fac0eba4abaa65636901522bc6bf;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

iwlwifi: mvm: update power after phy_ctxt is NULL when unassigning chanctx

iwl_mvm_power_update_mac() (more specifically
iwl_mvm_power_iterator()) relies on the phy_ctxt setting to decide
whether the vif is active or not.  When unassigning a chanctx, we
should therefore call iwl_mvm_power_update_mac() after setting
phy_chanctx to NULL.
