checkpatch: reversed logic with acpi test checks

[PATCH] checkpatch: reversed logic with acpi test checks

Posted by Michael S. Tsirkin 3 years, 11 months ago

Logic reversed: allowed list should just be ignored. Instead we
only take that into account :(

Queued with "!~" to achieve the logical not.

Hmm perl manual says "not" is the logical not. Weird.
What's !~? My perl is a bit rusty :)

man perlop says:
# Binary "!~" is just like "=~" except the return value is negated in
the logical sense.

So it's more idiomatic to use it directly rather than using =~ and then
doing a logical negation separately.
