[PATCH] of: Fix of_empty_ranges_quirk()

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

 



From: Marek Vasut <marek.vasut+renesas@xxxxxxxxx>

The of_empty_ranges_quirk() returns a mix of boolean and signed integer
types, which cannot work well. Replace that with boolean only and fix
usage logic in of_translate_one() -- the check should trigger when the
ranges are NULL and the quirk is applicable on the hardware.
