Subject: [PATCH] wifi: ath11k: ath11k_debugfs_register(): fix format-truncation warning
Date: Tue, 10 Oct 2023 09:22:50 +0300 [thread overview]
Message-ID: <20231010062250.2580951-1-kvalo@kernel.org> (raw)
From: Kalle Valo <quic_kvalo@quicinc.com>
In v6.6-rc4 with GCC 13.2 I see a new warning:
drivers/net/wireless/ath/ath11k/debugfs.c: In function 'ath11k_debugfs_register':
drivers/net/wireless/ath/ath11k/debugfs.c:1597:51: error: '%d' directive output may be truncated writing between 1 and 3 bytes into a region of size 2 [-Werror=format-truncation=]
drivers/net/wireless/ath/ath11k/debugfs.c:1597:48: note: directive argument in the range [0, 255]
drivers/net/wireless/ath/ath11k/debugfs.c:1597:9: note: 'snprintf' output between 5 and 7 bytes into a destination of size 5
Increase the size of pdev_name to 10 bytes to make sure there's enough room for
the string. Also change the format to '%u' as ar->pdev_idx is u8.
Compile tested only.
