[PATCH] net: bluetooth: Use kzalloc instead of kmalloc/memset

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

 



Use kzalloc rather than duplicating its implementation, which makes code
simple and easy to understand.

./net/bluetooth/hci_conn.c:2038:6-13: WARNING: kzalloc should be used for cp, instead of kmalloc/memset.
