[PATCH] ppp: Remove redundant BUG_ON() check in ppp_pernet

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


Passing NULL to ppp_pernet causes a crash via BUG_ON.
Dereferencing net in net_generici() also has the same effect.
This patch removes the redundant BUG_ON check on the same parameter.
