kbuild: replace $(if A,A,B) with $(or A,B)

2022-02-15T03:25:56Z

$(or ...) is available since GNU Make 3.81, and useful to shorten the code in some places. Covert as follows: $(if A,A,B) --> $(or A,B) This patch also converts: $(if A, A, B) --> $(or A, B) Strictly speaking, the latter is not an equivalent conversion because GNU Make keeps spaces after commas; if A is not empty, $(if A, A, B) expands to " A", while $(or A, B) expands to "A". Anyway, preceding spaces are not significant in the code hunks I touched. Signed-off-by: Masahiro Yamada Reviewed-by: Nicolas Schier

spi: tools: make a symbolic link to the header file spi.h

2021-04-22T15:30:39Z

The header file spi.h in include/uapi/linux/spi is needed for spidev.h, so we also need make a symbolic link to it to eliminate the error message as below: In file included from spidev_test.c:24: include/linux/spi/spidev.h:28:10: fatal error: linux/spi/spi.h: No such file or directory 28 | #include | ^~~~~~~~~~~~~~~~~ compilation terminated.

Fix the following sparse warning: ./spidev_test.c:50:9: warning: symbol 'default_tx' was not declared. Should it be static? ./spidev_test.c:59:9: warning: symbol 'default_rx' was not declared.

spi: spidev_test: Use %u to format unsigned numbers

2020-06-08T12:42:44Z

Consistently use %u to format unsigned numbers. For "bits" this doesn't matter that much, as it is "uint8_t". However, "speed" is "uint32_t", so in case people use "-s -1" to force the maximum, they would see: max speed: -1 Hz (4294967 KHz) While at it, use "k" (kilo) instead of "K" (kelvin) in "kHz".

spi: spidev_test: Remove hidden temporary file when make clean

In the current code, it only removes *.o and .*.o.d file when make clean, there still exists useless .*.o.cmd file, just remove it.

Merge tag 'spdx-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx

2020-04-03T20:12:26Z

Pull SPDX updates from Greg KH: "Here are three SPDX patches for 5.7-rc1. One fixes up the SPDX tag for a single driver, while the other two go through the tree and add SPDX tags for all of the .gitignore files as needed. Nothing too complex, but you will get a merge conflict with your current tree, that should be trivial to handle (one file modified by two things, one file deleted.) All three of these have been in linux-next for a while, with no reported issues other than the merge conflict" * tag 'spdx-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx: ASoC: MT6660: make spdxcheck.py happy .gitignore: add SPDX License Identifier .gitignore: remove too obvious comments

spi: spidev_test: Use perror() only if errno is not 0

2020-02-13T13:17:39Z

It is better to use perror() only if errno is not 0, it should use printf() when errno is 0, otherwise there exists redudant ": Success". E.g. without this patch: $ ./spidev_test -p 1234 --input test.bin only one of -p and --input may be selected: Success Aborted (core dumped) With this patch: $ ./spidev_test -p 1234 --input test.bin only one of -p and --input may be selected Aborted (core dumped) Signed-off-by: Tiezhu Yang Reviewed-by: Geert Uytterhoeven Link: https://lore.kernel.org/r/1581567368-8055-3-git-send-email-yangtiezhu@loongson.cn Signed-off-by: Mark Brown
