From 9373771aaed17f5c2c38485f785568abe3a9f8c1 Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Sun, 9 Jul 2023 06:31:54 -0700 Subject: [PATCH] wifi: airo: avoid uninitialized warning in airo_get_rate() Quieten a gcc (11.3.0) build error or warning by checking the function call status and returning -EBUSY if the function call failed. This is similar to what several other wireless drivers do for the SIOCGIWRATE ioctl call when there is a locking problem. drivers/net/wireless/cisco/airo.c: error: 'status_rid.currentXmitRate' is used uninitialized [-Werror=uninitialized] Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Signed-off-by: Randy Dunlap Reported-by: Geert Uytterhoeven Link: https://lore.kernel.org/r/39abf2c7-24a-f167-91da-ed4c5435d1c4@linux-m68k.org Link: https://lore.kernel.org/r/20230709133154.26206-1-rdunlap@infradead.org Signed-off-by: Jakub Kicinski --- drivers/net/wireless/cisco/airo.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/drivers/net/wireless/cisco/airo.c b/drivers/net/wireless/cisco/airo.c index 7c4cc5f5e1eb..dbd13f7aa3e6 100644 --- a/drivers/net/wireless/cisco/airo.c +++ b/drivers/net/wireless/cisco/airo.c @@ -6157,8 +6157,11 @@ static int airo_get_rate(struct net_device *dev, struct iw_param *vwrq = &wrqu->bitrate; struct airo_info *local = dev->ml_priv; StatusRid status_rid; /* Card status info */ + int ret; - readStatusRid(local, &status_rid, 1); + ret = readStatusRid(local, &status_rid, 1); + if (ret) + return -EBUSY; vwrq->value = le16_to_cpu(status_rid.currentXmitRate) * 500000; /* If more than one rate, set auto */ -- 2.25.1
