2021-08-26nfc: mrvl: remove unused header includesKrzysztof Kozlowski1-3/+0
Do not include unnecessary headers. Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-07-30nfc: mrvl: correct nfcmrvl_spi_parse_dt() device_node argumentKrzysztof Kozlowski1-1/+1
The device_node in nfcmrvl_spi_parse_dt() cannot be const as it is passed to OF functions which modify it. Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2021-07-29nfc: mrvl: constify static nfcmrvl_if_opsKrzysztof Kozlowski1-1/+1
File-scope struct nfcmrvl_if_ops is not modified so can be made const. Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-07-29nfc: mrvl: constify several pointersKrzysztof Kozlowski1-2/+2
Several functions do not modify pointed data so arguments and local variables can be const for correctness and safety. Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Use SPDX-License-Identifier: GPL-2.0-only, instead of hand writing it. Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com> Link: https://lore.kernel.org/r/20210531073522.6720-3-krzysztof.kozlowski@canonical.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2021-05-29nfc: mrvl: mark OF device ID tables as maybe unusedKrzysztof Kozlowski1-1/+1
The driver can match either via OF or I2C ID tables. If OF is disabled, the table will be unused: drivers/nfc/nfcmrvl/spi.c:199:34: warning: ‘of_nfcmrvl_spi_match’ defined but not used [-Wunused-const-variable=] Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com> Link: https://lore.kernel.org/r/20210528124200.79655-5-krzysztof.kozlowski@canonical.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2021-05-24NFC: nfcmrvl: fix kernel-doc syntax in file headersAditya Srivastava1-1/+1
The opening comment mark '/**' is used for highlighting the beginning of kernel-doc comments. The header for drivers/nfc/nfcmrvl follows this syntax, but the content inside does not comply with kernel-doc. This line was probably not meant for kernel-doc parsing, but is parsed due to the presence of kernel-doc like comment syntax(i.e, '/**'), which causes unexpected warnings from kernel-doc. For e.g., running scripts/kernel-doc -none on drivers/nfc/nfcmrvl/spi.c causes warning: warning: expecting prototype for Marvell NFC(). Prototype was for SPI_WAIT_HANDSHAKE() instead Provide a simple fix by replacing such occurrences with general comment format, i.e. '/*', to prevent kernel-doc from parsing it.

2017-04-02NFC: nfcmrvl: double free on error pathDan Carpenter1-3/+2
The nci_spi_send() function calls kfree_skb(skb) on both error and success so this extra kfree_skb() is a double free. Fixes: caf6e49bf6d0 ("NFC: nfcmrvl: add spi driver") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2017-04-02NFC: nfcmrvl: drop duplicate header gpio.hGeliang Tang1-1/+0
Drop duplicate header gpio.h from nfcmrvl/spi.c. Signed-off-by: Geliang Tang <geliangtang@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2015-10-27NFC: nfcmrvl: update device tree bindings for Marvell NFCVincent Cuissard1-1/+1
Align NFC bindgins to use marvell instead of mrvl. Signed-off-by: Vincent Cuissard <cuissard@marvell.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2015-10-27NFC: nfcmrvl: add spi driverVincent Cuissard1-0/+228
