2021-05-23NFC: nfcmrvl: fix kernel-doc syntax in file headersAditya Srivastava
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.

2021-05-19nfc: s3fwrn5: i2c: Enable optional clock from device treeStephan Gerhold
S3FWRN5 depends on a clock input ("XI" pin) to function properly. Depending on the hardware configuration this could be an always-on oscillator or some external clock that must be explicitly enabled. So far we assumed that the clock is always-on. Make the driver request an (optional) clock from the device tree and make sure the clock is running before starting S3FWRN5. Note: S3FWRN5 asserts "GPIO2" whenever it needs the clock input to function correctly. On some hardware configurations, GPIO2 is connected directly to an input pin of the external clock provider (e.g. the main PMIC of the SoC). In that case, it can automatically AND the clock enable bit and clock request from S3FWRN5 so that the clock is actually only enabled when needed. It is also conceivable that on some other hardware configuration S3FWRN5's GPIO2 might be connected as a regular GPIO input of the SoC. In that case, follow-up patches could extend the driver to request the GPIO, set up an interrupt and only enable the clock when requested by S3FWRN5.

2021-02-09mei: bus: change remove callback to return voidUwe Kleine-König
The driver core ignores the return value of mei_cl_device_remove() so passing an error value doesn't solve any problem. As most mei drivers' remove callbacks return 0 unconditionally and returning a different value doesn't have any effect, change this prototype to return void and return 0 unconditionally in mei_cl_device_remove(). The only driver that could return an error value is modified to emit an explicit warning in the error case.

2020-11-20crypto: sha - split sha.h into sha1.h and sha2.hEric Biggers
Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2, and <crypto/sha3.h> contains declarations for SHA-3. This organization is inconsistent, but more importantly SHA-1 is no longer considered to be cryptographically secure. So to the extent possible, SHA-1 shouldn't be grouped together with any of the other SHA versions, and usage of it should be phased out. Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and <crypto/sha2.h>, and make everyone explicitly specify whether they want the declarations for SHA-1, SHA-2, or both. This avoids making the SHA-1 declarations visible to files that don't want anything to do with SHA-1. It also prepares for potentially moving sha1.h into a new insecure/ or dangerous/ directory.

2020-09-10nfc: s3fwrn5: Add missing CRYPTO_HASH dependencyKrzysztof Kozlowski
The driver uses crypto hash functions so it needs to select CRYPTO_HASH. This fixes build errors: arc-linux-ld: drivers/nfc/s3fwrn5/firmware.o: in function `s3fwrn5_fw_download': firmware.c:(.text+0x152): undefined reference to `crypto_alloc_shash' Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-09-10nfc: s3fwrn5: Remove unneeded 'ret' variableKrzysztof Kozlowski
The local variable 'ret' can be removed: drivers/nfc/s3fwrn5/i2c.c:167:6: warning: variable 'ret' set but not used [-Wunused-but-set-variable] Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-09-10nfc: s3fwrn5: Remove wrong vendor prefix from GPIOsKrzysztof Kozlowski
The device tree property prefix describes the vendor, which in case of S3FWRN5 chip is Samsung. Therefore the "s3fwrn5" prefix for "en-gpios" and "fw-gpios" is not correct and should be deprecated. Introduce properly named properties for these GPIOs but still support deprecated ones.

We got slightly different patches removing a double word in a comment in net/ipv4/raw.c - picked the version from net. Simple conflict in drivers/net/ethernet/ibm/ibmvnic.c. Use cached values instead of VNIC login response buffer (following what commit 507ebe6444a4 ("ibmvnic: Fix use-after-free of VNIC login response buffer") did).
