Subject: [PATCH 05/12] nfc: virtual_ncidev: constify pointer to nfc_dev
Date: Thu, 29 Jul 2021 12:40:15 +0200 [thread overview]
Message-ID: <20210729104022.47761-6-krzysztof.kozlowski@canonical.com> (raw)
In-Reply-To: <20210729104022.47761-1-krzysztof.kozlowski@canonical.com>
virtual_ncidev_ioctl() does not modify struct nfc_dev, so local variable
can be a pointer to const.
