Subject: [PATCH 3/5] staging: rtl8723bs: Remove set but not used variable 'prwskeylen'
Date: Sun, 6 Oct 2019 17:09:57 +0800	[thread overview]
Message-ID: <1570352999-45790-4-git-send-email-zhengbin13@huawei.com> (raw)
In-Reply-To: <1570352999-45790-1-git-send-email-zhengbin13@huawei.com>

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/staging/rtl8723bs/core/rtw_security.c: In function rtw_tkip_encrypt:
drivers/staging/rtl8723bs/core/rtw_security.c:660:6: warning: variable prwskeylen set but not used [-Wunused-but-set-variable]
drivers/staging/rtl8723bs/core/rtw_security.c: In function rtw_tkip_decrypt:
drivers/staging/rtl8723bs/core/rtw_security.c:768:6: warning: variable prwskeylen set but not used [-Wunused-but-set-variable]
drivers/staging/rtl8723bs/core/rtw_security.c: In function rtw_aes_encrypt:
drivers/staging/rtl8723bs/core/rtw_security.c:1528:6: warning: variable prwskeylen set but not used [-Wunused-but-set-variable]

It is not used since commit 554c0a3abf21 ("staging:
Add rtl8723bs sdio wifi driver")
