From 351f2bfe6362c663f45f5c6111f14365cfd094ab Mon Sep 17 00:00:00 2001 From: "Kory Maincent (Dent Project)" Date: Thu, 21 Nov 2024 15:42:28 +0100 Subject: [PATCH] regulator: core: Ignore unset max_uA constraints in current limit check We should only consider max_uA constraints if they are explicitly defined. In cases where it is not set, we should assume the regulator has no current limit.
