[patch] crypto: cleanup: remove unneeded null check

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

 



We don't check "frontend" consistently in crypto_init_spawn2().  We
check it at the start of the function but then we dereference it 
unconditionally in the parameter list when we call crypto_init_spawn().

I looked at the places that call crypto_init_spawn2() and "frontend" is
always a valid pointer so I removed the check for null.
