[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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

drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c: In function rtl8xxxu_c2hcmd_callback:
drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c:5396:24: warning: variable vif set but not used [-Wunused-but-set-variable]

They are introduced by commit e542e66b7c2e ("rtl8xxxu:
add bluetooth co-existence support for single antenna"), but never used,
so remove them.
