Subject: [PATCH 07/12] nfc: constify pointer to nfc_vendor_cmd
Date: Sat, 24 Jul 2021 23:49:23 +0200	[thread overview]
Message-ID: <20210724214928.122096-2-krzysztof.kozlowski@canonical.com> (raw)
In-Reply-To: <20210724214743.121884-1-krzysztof.kozlowski@canonical.com>

Neither the core nor the drivers modify the passed pointer to struct
nfc_vendor_cmd, so make it a pointer to const for correctness and
safety.
