Subject: [PATCH 01/12] nfc: constify payload argument in nci_send_cmd()
Date: Sat, 24 Jul 2021 23:47:32 +0200	[thread overview]
Message-ID: <20210724214743.121884-2-krzysztof.kozlowski@canonical.com> (raw)
In-Reply-To: <20210724214743.121884-1-krzysztof.kozlowski@canonical.com>

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.
