[PATCH 01/12] nfc: constify payload argument in nci_send_cmd()

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

 



The nci_send_cmd() payload argument is passed directly to skb_put_data()
which already accepts a pointer to const, so make it const as well for
correctness and safety.
