BTW, Javier's email is different. All you previous mails bounced. I
cc-ed here the proper one.

I think Krzysztof already mentioned but a commit message shouln't
describe what the change is (one can look to the patch for that)
but why the change is needed.
So I would had expect something along these lines:
Many Exynos boards (i.e: the Exynos5422 Odroid XU3/XU4) have GPIO
and PWM based LEDs, so enable the needed Kconfig options to have
support for these. Also, some boards use the heartbeat LED trigger
so enable support for this as well.

I don't see an Exynos board using the timer trigger. Do you need it for
some user-space application that uses the sysfs interface? I'm OK with
enabling it but again this should be mentioned in the commit message.

Earlier design of the LED for Odroid XU3 was using gpio-leds
Now It was change to using both pwm-leds and gpio-leds.
Earlier I kept them as loadable module and now build-in.
Should I resend this again. Or some body will update the commit message.

I know that Odroid XU3 have both LEDs connected to GPIO and

Yes, because exynos_defconfig as everything as built-in to
make it easier for developers to test by only copying the
kernel image and not the modules.

If a patch has a typo, an extra blank line or something
very easy to fix then it may be possible that the maintainer
will do the fix when applying but changing the commit message
I think is too much so in this case is better to resend IMHO.
