nfc: microread: drop unneeded debug prints

2021-10-12T00:00:52Z

ftrace is a preferred and standard way to debug entering and exiting functions so drop useless debug prints. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Jakub Kicinski

nfc: microread: drop unneeded memory allocation fail messages

2021-09-13T13:38:32Z

nfc_mei_phy_alloc() already prints an error message on memory allocation failure. Signed-off-by: Krzysztof Kozlowski Signed-off-by: David S. Miller

nfc: microread: remove unused header includes

Do not include unnecessary headers. Signed-off-by: Krzysztof Kozlowski Signed-off-by: David S. Miller

nfc: microread: constify several pointers

2021-07-29T11:28:03Z

Several functions do not modify pointed data so arguments and local variables can be const for correctness and safety. Signed-off-by: Krzysztof Kozlowski Signed-off-by: David S. Miller

nfc: constify nfc_hci_ops

2021-07-25T08:21:21Z

Neither the core nor the drivers modify the passed pointer to struct nfc_hci_ops, so make it a pointer to const for correctness and safety. Signed-off-by: Krzysztof Kozlowski Signed-off-by: David S. Miller

nfc: constify nfc_hci_gate

2021-07-25T08:21:21Z

Neither the core nor the drivers modify the passed pointer to struct nfc_hci_gate, so make it a pointer to const for correctness and safety. Signed-off-by: Krzysztof Kozlowski Signed-off-by: David S. Miller

nfc: constify nfc_phy_ops

2021-07-25T08:21:21Z

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 Signed-off-by: David S. Miller

NFC: microread: Remove redundant assignment to variable err

2021-06-01T23:58:38Z

In the case MICROREAD_CB_TYPE_READER_ALL clang reports a dead code warning. The error code assigned to variable err is already passed to async_cb(). The assignment is redundant and can be removed.

mei: bus: change remove callback to return void

2021-02-09T08:30:16Z

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.

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21Z

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada
