From e43f50139c356a4cece55926231a33052e234f8b Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Wed, 22 Apr 2015 14:34:48 +0100 Subject: [PATCH] mfd: arizona: Remove redundant register sync This soft reset used to be located after the register patch had been applied, but has since moved to before the patch is applied. At the new location there is no requirement to do a register sync as no register writes will have happened yet.
