Dell Precision 7780 often wakes up on its own from suspend. Sometimes
wake up happens immediately (i. e. within 7 seconds), sometimes it happens
after, say, 30 minutes.

Thanks for the patch, it looks quite good. See my comments below.

I believe it's the same person in both cases as the author of the patch.
As Bart said, just drop these tags, it makes little sense to have them.

Not sure if we also want BIOS version, probably it's more important than Board
Name, but okay, we may not know without trying if any other users need the same
quirk or will suffer from it (if BIOS version is different).

With tags removed, feel free to add my
Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

Note, it's your responsibility to carry the given tags as long as there were
no significant changes in the patch. That said, I expect to see a v2
without your 2 tags and with mine that I gave above. No code changes for now.

Hi!

Thanks for the patch.

Please don't add Tested-by, Reported-by, etc. if you're the author of the.
Tested-by should be added by someone else who tested your patch, it doesn't
make much sense otherwise because I sure do expect you test your changes if
you have access to the right hardware. :)

Looks good to me, but I'll give GPIO ACPI maintainers time to chime in.
