Subject: [PATCH 03/12] nfc: s3fwrn5: constify nci_ops
Date: Sat, 24 Jul 2021 23:47:34 +0200	[thread overview]
Message-ID: <20210724214743.121884-4-krzysztof.kozlowski@canonical.com> (raw)
In-Reply-To: <20210724214743.121884-1-krzysztof.kozlowski@canonical.com>

s3fwrn5 driver modifies static struct nci_ops only to set prop_ops.
Since prop_ops is build time constant with known size, it can be made
const.  This allows to removeo the function setting the prop_ops -
s3fwrn5_nci_get_prop_ops().
