spi: tools: Make default_tx/rx and input_tx static

2020-06-11T15:27:24+00:00

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. Should it be static?
./spidev_test.c:60:6: warning: symbol 'input_tx' was not declared. Should it be static?

spi: spidev_test: Use %u to format unsigned numbers

2020-06-08T12:42:44+00:00

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: Use perror() only if errno is not 0

2020-02-13T13:17:39+00:00

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)

spi: spidev_test: Check input_tx and input_file first after parse options

2020-02-13T13:17:19+00:00

It is better to check input_tx and input_file first after parse options.
Otherwise, it will do some useless operations when both -p and --input
are selected.

spi: spidev_test: Remove break after exit statement

2020-02-13T13:16:59+00:00

When call print_usage() in parse_opts(), it will exit directly.
Since break is not useful after exit statement, remove it.

spi: spidev_test: Improve decoded text part of hex dump

2018-09-04T16:00:37+00:00

- Print spaces as spaces,
  - Do not print characters > 126, as they will be shown as garbage
    in the modern UTF-8 era,
  - Use a normal period instead of its hexadecimal ASCII value,
  - Delimit the text part with pipe symbols on both sides (was left side
    only), without any spaces, to make it clear where the decoded text
    starts and ends,
  - Drop a useless comment.

spi: spidev_test: Fix input file check when transferring file

2016-11-04T15:56:09+00:00

Check the input file fd instead of spidev fd.
The spidev fd is supposed to be OK otherwise the transfer_file() function
would not be called at all.
