Hi Lee,

After merging the mfd tree, today's linux-next build (x86_64 allmodconfig)
produced this warning:

drivers/leds/leds-pm8058.c: In function 'pm8058_led_probe':
drivers/leds/leds-pm8058.c:109:17: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
  led->ledtype = (u32)of_device_get_match_data(&pdev->dev);
                 ^

Exposed by commit

  deed10c2d603 ("mfd: pm8xxx: Make elegible for COMPILE_TEST")

CONFIG_LEDS_PM8058 depends on CONFIG_MFD_PM8XXX which is now turned on
by allmodconfig.

The actual problematic commit is:

  7f866986e705 ("leds: add PM8058 LEDs driver")

from v4.9-rc1.

The pointer returned by of_device_get_match_data() doesn't have the same
size as u32 on 64-bit architectures, causing issues when compile testing
the driver on such platform. Make ledtype unsigned long instead, to
solve this problem.

Hi Bjorn,

(Nice to see you) :)

I'm going to apply this *before* Linus' fix.

Applied, thanks.

Ummm... no?

extern const void *of_device_get_match_data(const struct device *dev);

Make it void *. u32 is buggy. unsigned long is merely ugly code. void
* is not nice, but certainly better than unsigned long.

unsigned long is correct, see below:

static const struct of_device_id pm8058_leds_id_table[] = {
        {
                .compatible = "qcom,pm8058-led",
                .data = (void *)PM8058_LED_TYPE_COMMON
        },
        {
                .compatible = "qcom,pm8058-keypad-led",
                .data = (void *)PM8058_LED_TYPE_KEYPAD
        },
        {
                .compatible = "qcom,pm8058-flash-led",
                .data = (void *)PM8058_LED_TYPE_FLASH
        },
        { },
};

of_device_get_match_data will return PM8058_LED_TYPE_*
which clearly is a led type identifier.

Thus unsigned long looks reasonable.

Right, this returns a pointer, which is of architecture dependent size.

unsigned long is the integer type in the kernel that has the same size
as a pointer, similar to the C-standard's intptr_t. So this is the
idiomatic way to pass an integer data type via a pointer variable in the
kernel.

Hmm. Ok. So u32 would actually make even more sense there (because
PM8058_LED_TYPE_* does not really need to be 64-bit), but it would
cause a warning.

I don't like this. This fix actually makes code waste memory and is
uglier.

...but we get a warning fix. So I don't like the patch, but it is an
improvement...

Yes, that should work. It would actually be my preferred solution.

I'm fine with this suggestion, and it silence the warning. I will update
and resend the patch.

The pointer returned by of_device_get_match_data() doesn't have the same
size as u32 on 64-bit architectures, causing a compile warning when
compile-testing the driver on such platform.

Cast the return value of of_device_get_match_data() to unsigned long and
then to u32 to silence this warning.

Right, hence why I said I'd sent out a pull-request.

The problem, however, arose due to a change in its parent driver's
Kconfig entry, which has been applied to the MFD tree.  We need to
ensure this patch is applied *before* the other 'fix' to quash the
warning before it starts, so to speak.

Wouldn't (u32)(void *) be even more correct?

... if the compiler will let you get away with it.

Afaict that would still produce the warning. of_device_get_match_data
already returns void *.

Just tested.  It actually still suffers from the original error.

warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
