From 758d1a8a8af04c70addb26761796019df267f420 Mon Sep 17 00:00:00 2001 From: Luca Coelho Date: Wed, 9 Nov 2016 10:02:46 +0200 Subject: [PATCH] iwlwifi: mvm: mark ret as maybe_unused in iwl_dbgfs_fw_restart_write() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The value returned from iwl_mvm_send_cmd_pdu() in this function is not used and always returns an error (which is the whole point of the call). 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 --- drivers/net/wireless/intel/iwlwifi/mvm/debugfs.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) 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); -- 2.20.1
