From f74521ca578f38daa3e800efde7fdb2ac3ba76ef Mon Sep 17 00:00:00 2001 From: MyungJoo Ham Date: Mon, 8 May 2017 05:45:44 +0000 Subject: regulator: max8997/8966: fix charger cv voltage set bug When min charger-CV is <= 4.0V and max charger-CV is >= 4.0V, we can use 4.00V as CV (register value = 0x1).` The original code had a typo that wrote ">=" (max_uV >= 4000000), which should've been "<", which is not necessary anyway as mentioned by Dan Carpenter.
