[PATCH net] Bluetooth: SMP: remove set but not used variable 'smp'

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

 



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

net/bluetooth/smp.c: In function 'smp_irk_matches':
net/bluetooth/smp.c:505:18: warning:
 variable 'smp' set but not used [-Wunused-but-set-variable]

net/bluetooth/smp.c: In function 'smp_generate_rpa':
net/bluetooth/smp.c:526:18: warning:
 variable 'smp' set but not used [-Wunused-but-set-variable]

It is not used since commit 28a220aac596 ("bluetooth: switch
to AES library")
