Subject: [PATCH 1/2] iwlwifi: mvm: Fix the build of mvm/mac-ctxt.c with debugfs disabled


When attempting to build my kernel I get:
  CC      drivers/net/wireless/iwlwifi/mvm/mac-ctxt.o
 drivers/net/wireless/iwlwifi/mvm/mac-ctxt.c: In function ‘iwl_mvm_beacon_loss_iterator’:
 drivers/net/wireless/iwlwifi/mvm/mac-ctxt.c:1378:30: error: ‘struct iwl_mvm_vif’ has no member named ‘mvm’

Fix that by making the new code depend on IWLWIFI_DEBUGFS as the
definition of mvm in struct iwl_mvm_if does.

Cc: Emmanuel Grumbach <emmanuel.grumbach@...el.com>
Fixes: 9d761fd8a58360e iwlwifi: mvm: add trigger for firmware dump upon missed beacons
