2021-07-29nfc: fdp: constify several pointersKrzysztof Kozlowski1-1/+1
Several functions do not modify pointed data so arguments and local variables can be const for correctness and safety. This allows also making file-scope nci_core_get_config_otp_ram_version array const. Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com> Signed-off-by: David S.

2021-07-25nfc: constify nfc_phy_opsKrzysztof Kozlowski1-1/+1
Neither the core nor the drivers modify the passed pointer to struct nfc_phy_ops (consisting of function pointers), so make it a pointer to const for correctness and safety. Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-05-31nfc: fdp: drop ftrace-like debugging messagesKrzysztof Kozlowski1-1/+0
Now that the kernel has ftrace, any debugging calls that just do "made it to this function!" and "leaving this function!" can be removed. Better to use standard debugging tools. This allows also to remove several local variables and entire fdp_nci_recv_frame() function (whose purpose was only to log).
