An appropriately named unsigned long is added, and the assignments as well as error checking fixed up. API conformance testing for completions with coccinelle spatches are being used to locate API usage inconsistencies: ./drivers/net/wireless/ath/carl9170/usb.c:675 int return assigned to unsigned long Patch was compile tested with x86_64_defconfig + CONFIG_ATH_CARDS=m, CONFIG_CARL9170=m Patch is against 4.1-rc3 (localversion-next is -next-20150512) Signed-off-by: Nicholas Mc Guire Acked-by: Christian Lamparter Signed-off-by: Kalle Valo --- diff --git a/drivers/net/wireless/ath/carl9170/usb.c b/drivers/net/wireless/ath/carl9170/usb.c index c9f93310c0d6..76842e6ca38e 100644 --- a/drivers/net/wireless/ath/carl9170/usb.c +++ b/drivers/net/wireless/ath/carl9170/usb.c @@ -651,6 +651,7 @@ int carl9170_exec_cmd(struct ar9170 *ar, const enum carl9170_cmd_oids cmd, unsigned int plen, void *payload, unsigned int outlen, void *out) { int err = -ENOMEM; + unsigned long time_left; if (!IS_ACCEPTING_CMD(ar)) return -EIO; @@ -672,8 +673,8 @@ int carl9170_exec_cmd(struct ar9170 *ar, const enum carl9170_cmd_oids cmd, err = __carl9170_exec_cmd(ar, &ar->cmd, false); if (!(cmd & CARL9170_CMD_ASYNC_FLAG)) { - err = wait_for_completion_timeout(&ar->cmd_wait, HZ); - if (err == 0) { + time_left = wait_for_completion_timeout(&ar->cmd_wait, HZ); + if (time_left == 0) { err = -ETIMEDOUT; goto err_unbuf; }
