While running kselftest recently added gpio gpio-sim.sh test case the following warning was triggered on Linux next tag 20210330 tag running on arm64 juno and hikey devices.
GOOD: next-20210326 BAD: next-20210330
This is still happening today on Linux next tag 20210407.
Can you add the following
sysfs_attr_init(attrs[i]);
to the end of the loop in gpio_sim_setup_sysfs()?
Do you mean like this,
diff --git a/drivers/gpio/gpio-sim.c b/drivers/gpio/gpio-sim.c index ea17289a869c..5fe67ccf45f7 100644 --- a/drivers/gpio/gpio-sim.c +++ b/drivers/gpio/gpio-sim.c @@ -296,6 +296,7 @@ static int gpio_sim_setup_sysfs(struct gpio_sim_chip *chip) dev_attr->store = gpio_sim_sysfs_line_store;
attrs[i] = &dev_attr->attr;
sysfs_attr_init(attrs[i]); } chip->attr_group.name = "line-ctrl";Precisely.
As per your suggestions the above line added and build tested the reported issue is fixed now.

If it fixes an issue I'll send a formal patch.
I will build and test this and report here.
OTOH, LKFT builds kernel and rootfs on host and runs tests on various target devices. While doing this process "make install" is not installing required test files like gpio-mockup-cdev and gpio-line-name.
