Subject: [PATCH 11/12] nfc: constify nfc_llc_ops
Date: Sat, 24 Jul 2021 23:49:27 +0200 [thread overview]
Message-ID: <20210724214928.122096-6-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_llc_ops, so make it a pointer to const for correctness and safety.

The llc must be registered with nfc before it can be used. Do that by
calling::
- nfc_llc_register(const char *name, struct nfc_llc_ops *ops);
+ nfc_llc_register(const char *name, const struct nfc_llc_ops *ops);
Again, note that the llc does not handle the physical link. It is thus very
easy to mix any physical link with any llc for a given chip driver.
