Re: [PATCH 1/3 v4] thermal: samsung: correct the fall interrupt en, status bit fields

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Hi,

All patches (#1-#3) look good to me, FWIW you can add:

	Reviewed-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@xxxxxxxxxxx>

Please note that (at least) patch #3 conflicts with Lukasz's EXYNOS4412
fixup patchset:

	https://lkml.org/lkml/2013/10/9/35

It is up to Eduardo to resolve this but it probably would be better to
merge EXYNOS4412 fixes first and then add EXYNOS5420 support. This would
require you to port patch #3 over Lukasz's patchset though.

Best regards,
