Tag the ret variable with __maybe_unused to avoid this compile warning when W=1 is used: /home/luca/iwlwifi/stack-dev/drivers/net/wireless/intel/iwlwifi/mvm/debugfs.c: In function ‘iwl_dbgfs_fw_restart_write’: /home/luca/iwlwifi/stack-dev/drivers/net/wireless/intel/iwlwifi/mvm/debugfs.c:875:6: warning: variable ‘ret’ set but not used [-Wunused-but-set-variable] int ret; ^ Signed-off-by: Luca Coelho --- diff --git a/drivers/net/wireless/intel/iwlwifi/mvm/debugfs.c b/drivers/net/wireless/intel/iwlwifi/mvm/debugfs.c index 7b7d2a146e30..a260cd503200 100644 --- a/drivers/net/wireless/intel/iwlwifi/mvm/debugfs.c +++ b/drivers/net/wireless/intel/iwlwifi/mvm/debugfs.c @@ -798,7 +798,7 @@ static ssize_t iwl_dbgfs_drv_rx_stats_read(struct file *file, static ssize_t iwl_dbgfs_fw_restart_write(struct iwl_mvm *mvm, char *buf, size_t count, loff_t *ppos) { - int ret; + int __maybe_unused ret; mutex_lock(&mvm->mutex);
