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


When attempting to build my kernel I get:

 CC      drivers/net/wireless/iwlwifi/mvm/phy-ctxt.o
 drivers/net/wireless/iwlwifi/mvm/phy-ctxt.c: In function ‘iwl_mvm_phy_ctxt_cmd_data’:
 drivers/net/wireless/iwlwifi/mvm/phy-ctxt.c:178:6: error: ‘struct iwl_mvm’ has no member named ‘dbgfs_rx_phyinfo’
 drivers/net/wireless/iwlwifi/mvm/phy-ctxt.c:179:23: error: ‘struct iwl_mvm’ has no member named ‘dbgfs_rx_phyinfo’
make[6]: *** [drivers/net/wireless/iwlwifi/mvm/phy-ctxt.o] Error 1

Fix it by making the new code depend on debugfs.

Fixes: ddf89ab10a93e8b iwlwifi: mvm: allow to force the Rx chains from debugfs
